Trees
A tiger
Some bird
Sun rays
Beetle
Answer:
sun rays
Explanation:
biotic factors are ones that are alive which are the tree, tiger, birds, and beetle. abiotic is the ones that are not alive which would be sun rays, air or water. hope this helps
In the image, the sun's rays are the abiotic factor. So the correct option is D.
What are abiotic factors?
All the non-living components or factors of an ecosystem are referred to as the Abiotic factors of that ecosystem. They are the chemical factors or the physical factors.
These are present either in the lithosphere, atmosphere, or hydrosphere. Examples of abiotic factors include sunlight, minerals, air, soil precipitation, and everything else that supports life but is not living.
These factors support life in the ecosystem. They help in the survival of the species and their reproduction in the ecosystem.
For example, without the required amount of sunlight, autotrophic photosynthetic organisms would not be able to perform photosynthesis. Thus it will result in their death. Since they are primary producers, the organisms dependent on them, called primary consumers will also die.
This effect will continue to cascade up the food chain and will eventually affect every organism.
Therefore the correct option is D.

What happens to all the weight of the food we eat? Where do the atoms in the food molecules go?
Answer:
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change.
Explanation:
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change.
What are the functions of small intestine?Three sections make up the small intestine: the jejunum, ileum, and duodenum. It aids in the continued digestion of stomach-derived food. It takes in water as well as vitamins, minerals, carbohydrates, fats, and proteins.
The digestion of food, absorption of body-needed nutrients, and elimination of waste are the primary functions of the small intestine.
The organ of the gastrointestinal tract known as the small intestine or small bowel is responsible for the majority of the absorption of nutrients from food. It receives bile and pancreatic juice and is located between the stomach and large intestine.

Microcystis aeruginosis is a freshwater photosynthetic cyanobacterium. When temperatures increase and nutrients are readily available in its pond habitat, M. aeruginosis undergoes rapid cell division and forms an extremely large, visible mass of cells called an algal bloom. M. aeruginosis has a short life span and is decomposed by aerobic bacteria and fungi. Identify the metabolic pathway and the organism that is primarily responsible for the change in oxygen level in the pond between times I and II AND between times III and IV.
Complete question:
You will find the figure with cyanobacteria, decomposers, and oxygen concentration curves in the attached files.
Answer:
- between times I - II: cyanobacteria produce oxygen through the procees of photosynthesis.
- between times II - III and III - IV: decomposers consume oxygen through the process of respiration.
Explanation:
Cyanobacteria, also known as green-blue algae, inhabits the euphotic stratum, producing oxygen through the process of photosynthesis. Probably they produce among 20 - 30% of the global photosynthetic activity. When they die, they sink to deeper water strata.
At the time I, the cyanobacteria population experiences a fast growth, which can be seen through the positive sharp increase of the curve slope. The curve reaches a maximum point just before time II, where it begins to decrease. Cyanobacteria reproduce, and the population grows in size. The more cells there are, the more photosynthetic activity, and the higher amount of oxygen is produced. Following cyanobacteria growth, there is an increase in oxygen concentration, which is reflected by the sharp increase in the curve slope. Both curves are very similar, but they are separated on time, meaning that first cyanobacteria need to reproduce and photosynthesize to posteriorly observe a proportional increase in oxygen concentrations.
Just before time II, the cyanobacteria population stops growing, and at time II begins a sharp decrease in size, reflected in the curve slope. Living cells still produce oxygen, but as there are fewer cells, oxygen concentration also decreases. Cyanobacteria are decomposed by aerobic bacteria and fungi. These last organisms consume oxygen through the process of respiration. As cyanobacteria die and are decomposed, aerobic cells can reproduce at higher rates, increasing their population size. This also can be seen reflected in the decomposers curve, which is stable until time II where it shows a sharp positive increase in its slope. As decomposers' population increases, they consume more oxygen, which concentration decreases inversely proportional to the decomposers' increase. This can be seen in the curves: from time II to time III, the aerobic organisms curve increases and the oxygen curve decreases, so as the cyanobacteria curve.
Just before time III cyanobacteria population stabilizes and during time IV keeps equal. Oxygen concentration keeps following, from time II to IV. When cyanobacteria stabilize, before time III, decomposers population starts to decrease, but they still consume oxygen.

According to the USDA, a "consists of a community of individuals who pledge support to a farm operation so that the farmland becomes,
either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits
of food production."
-sustainable operation
-farmers' market
-farmers' cooperative
-CSA
Answer:
The correct answer is CSA.
Explanation:
Community Supported Agriculture (CSA) is an alternative model for the distribution of agricultural products directly from the farmer to the consumer, it consists of a group of people who form a cooperative to grow and consume food. Through this socio-economic model, consumers lend their support to producers, in exchange for a direct and regular delivery of biological products, that is, producers and consumers support each other and share the benefits and risks of food production.

Answer:
if you find this helpful, Mark brainliest
Answer:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.
blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma.
blood group B – has B antigens with anti-A antibodies in the plasma.
blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
blood group AB – has both A and B antigens, but no antibodies.
Results from multiple experiments suggest that the ActA protein of Listeria, an integral membrane protein expressed on the cell surface, is the only bacterial protein that is required for the movement of the bacterium within its host cell. Which combination of the following observations shows that ActA is both, necessary and sufficient for bacterial movement?
I. ActA binds to the Arp2/3 complex
II. E. Coli in which ActA is expressed moves in host cell cytosol
III. Listeria lacking the ActA gene fail to move inside the host cell cytosol.
IV. ActA has 3 transmembrane domains
V. Arp2/3, when activated, nucleates a branched actin network
a. I and II
b. II and III
c. I and III
d. III and IV
e. I and V
Answer:
b. II and III
Explanation:
The Actin assembly-inducing (ActA) protein is an integral membrane protein localized on the bacterial surface. It has been shown that ActA is necessary and sufficient to induce bacterial movement within host cells, regardless of other proteins. The function of the ActA protein for bacterial movement within host cells was discovered by identifying mutant Listeria bacteria for the gene encoding this protein which were unable to spread from cell to cell. Subsequently, by inducing mutations in other genes of the bacterial genome, researchers discovered that actA was the only protein involved in the actin assembly, which is required for cell-to-cell spread.

Within a plant, photosynthesis is critical. It provides cells with the glucose they need for
energy. Photosynthesis is important for another reason, too. It's part of the flow of carbon
through organisms and the environment. This cycle, known as the carbon cycle, is essential
for life on Earth. It includes several processes that are occurring all the time. When plants
photosynthesize, carbon is removed from the atmosphere as carbon dioxide. When animals
and plants use cellular respiration, carbon is released into the atmosphere as carbon
dioxide. Organisms that die and are buried for millions of years turn into fossil fuels, which
are made of carbon. When humans burn those fossil fuels, carbon is released into the
atmosphere as carbon dioxide. Without enough carbon dioxide in the atmosphere, the
planet would be too cold. But too much carbon dioxide contributes to the warming of the
planet that could make it too hot to survive.
Based on the passage, what is one reason that the carbon cycle important?
A It adds carbon into the atmosphere whenever the level begins to drop too low.
B
It helps maintain a level of carbon in the atmosphere that is neither too hot nor
too cold.
с
It removes carbon from the atmosphere whenever the level begins to become
too high.
D
It releases carbon into space, preventing it from building up in Earth's
atmosphere.

which statement is an example of a feedback mechanism in humans
1.) increase in the level of blood sugar results in the pancreas increasing the amount of insulin it secretes
2.) increase exposure to pathogenic bacteria result in an increase in the number of red blood cells produced
3.) an increase in exercise results in a decrease in the rate of respiration
4.) increased muscle activity results in a decrease in heart rate
Answer:
1.
Explanation:
Controlling the level of sugar in the blood is an example of a feedback mechanism
The feedback mechanism man is a physiological regulation system that is found in a living body that works to return the body to the normal or earlier internal state. It is commonly called the homeostasis mechanism.
This feedback loop can be seen in any day-to-day function such as a rise in blood pressure levels, which results in the increase of insulin secretion in the body. An increase in physical activity leads to an increase in respiratory rate and the homeostatic mechanism will gradually lead to the body to the previous state.Thus the option 1 is correct.

Mecanismo de proteccion que posee el cuerpo que ocurre de forma pasiva a traves de la nariz?
Answer:
membrana mucosa que recubre las fosas nasales
Explanation:
Las fosas nasales se encuentran recubiertas por una membrana mucosa y unos pelos diminutos conocidos como cilios que ayudan a filtrar el aire que llega a los pulmones. Esta membrana posee dos tipos de mucosas: mucosa respiratoria y mucosa olfativa. La mucosa respiratoria de la cavidad nasal posee células caliciformes que secretan una sustancia llamada moco la cual tiene la finalidad de humedecer y calentar como así también de atrapar microorganismos patógenos/residuos del aire los cuales son finalmente removidos por los cilios que "barren" estas sustancias hacia la faringe. Por otra parte, la mucosa olfativa de la cavidad nasal se caracteriza por poseer células nerviosas olfativas las cuales forman parte del sentido del olfato.
Skin Our entire body is covered with a protective layer of epithelial cells. The layer of epithelial cells acts as the first line of

Answer:
d energy expenditure.
Explanation:
Basal metabolic rate is the body's resting rate of energy expenditure.
Simply stated, Basal metabolic rate describes the amount of calories that is required to keep the human body to function properly and perfectly at rest.
Calorie can be defined as a standard unit used for the measurement of the amount of energy present in foods and drinks.
Basal metabolic rate is the body's resting rate of a drive reduction is energy expenditure.
The BMR not entirely settled by roundabout calorimetry by estimating Q O 2 , the pace of oxygen utilization. In contrast to the BMR, the determination of the resting energy expenditure (REE) does not require a 12-hour fast.
Both BMR and RMR show the quantity of calories an individual consumes very still. If you're trying to control your weight, this information may be helpful. Calculating a person's BMR or RMR can help them determine how many calories they should cut out each day if they are trying to lose weight.
