Answer:
Not all the energy is passed from one level of the food chain to the next. About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.

In your own words wright a paragraph of the process of the respiratory system. 4-7 sentences
Answer:
First, you breathe in oxygen through your trachea. The air travels down through the trachea to your lungs. Then your lungs transport the oxygen through your pulmonary artery to your heart. Then the heart transports the oxidized blood throughout your body. Then once the blood gives away all the oxygen your veins take the filtered blood through your pulmonary vein and back to your lungs to get oxidized again. I hope this helps

In one cubic meter of the ocean, photosynthetic plankton produce 80,000 calories of energy each year. How many calories of energy are available in the bodies of the creatures that eat that plankton?
Select one:
a.
80,000
b.
8,000
c.
800
d.
80
8000 calories of energy are available in the bodies of the creatures that eat that plankton. Details about calories can be found below.
How to calculate energy available?In a natural habitat, living organisms feed on one another to derive energy needed for their metabolic activities.
However, only 10% of energy available is transferred to the organism because 90% (most) of the energy is used for the organism's metabolism.
According to this question, in one cubic meter of the ocean, photosynthetic plankton produce 80,000 calories of energy each year.
Therefore, 10/100 × 80,000 calories = 8,000 calories of energy are available in the bodies of the creatures that eat that plankton.

Explanation:
why photosynthesis is known as the pathway for energy
Answer:
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. It transforms light to chemical energy.
that's why it's called the pathway to energy.
Explanation:
hope it helps...
Life system: cyanobacteria begin photosynthesis and produce oxygen. Earth system: free oxygen reacts with rocks (axidation), resulting in increased rates of weathering for soil
production. Life system: land plants evolve and take root in terrestrial soil.
O Life system: cyanobacteria begin photosynthesis and produce oxygen. Earth system: free oxygen reacts with all available dissolved iron in the ocean. Life system: mass extinction
event of anaerobic organisms occurs from buildup of oxygen in the ocean.
• Earth system: oxygen moves from the ocean to the atmosphere through gas exchange. Earth system: free oxygen reacts with incoming solar radiation to form ozone. Earth system:
ozone collects in the stratosphere to form the protective ozone layer.
O Earth system: molten Earth forms into layers based on density and pull of gravity. Earth system: Earth cooled, and the water vapor in the atmosphere condensed and created the
oceans. Life system: cyanobacteria evolved.
The cyanobacteria were already there without the oxygen, so that rules out A, and a lot of prokaryotes were anaerobic, so that rules out Finally, Photosynthesis does not require oxygen. Instead, Oxygen is a waste product of it.
What is photosynthesis?Photosynthesis is a process that occurs in the chloroplast organelle of plant cells. The typical light reaction of photosynthesis takes place inside the thylakoid membrane of the chloroplast. The chief reactants such as water and carbon dioxide participate in the reaction. The water gets oxidized in the reaction to release oxygen as a product. The carbon dioxide gets reduced.
Thus, Photosynthesis is a process that occurs in the chloroplast organelle of plant cells

1. Why is most food digested?
A. Digestive enzymes require a variety of substrates.
B. It ensures that the diet is balanced.
C. Most ingested food molecules are large.
D. To prevent disorders of the intestine.
1. Why is most food digested?
C. Most ingested food molecules are large.
Food is digested to break down big particles of food into smaller ones so that the absorption process takes place more efficiently.
Answer:
C
Explanation:
As food molecules are very large during intake, they cannot be absorbed by the small intestine as macromolecules. They need to broken down into smaller molecules for absorption to take place.

How do geologists study direct evidence of Earth’s interior?
by collecting drill core samples of Earth’s crust
by measuring seismic wave activity
by analyzing how living things survive
by recording changes in climate patterns
Answer: A
Explanation: E2022
Geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option, as the seismic waves are waves of energy that travel through the earth's interior.
What are seismic waves?Geologists use various techniques to study the Earth's interior, but one of the most important is the measurement of seismic wave activity. Seismic waves are generated by various sources, such as earthquakes, volcanic eruptions, and human-made explosions. The waves travel through the earth's interior and can be detected by seismic instruments such as seismometers. Seismic waves come in two main types: body waves and surface waves. Body waves are waves that propagate through the earth's interior, while surface waves travel along the earth's surface. Body waves are further divided into two types: P-waves and S-waves.
Hence, geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option.

based on the data, what can you infer about the relative pH of the stomach?
The pH of stomach is important as it helps to induce the digestive enzyme called pepsin. The presence of HCL i.e., hydrochloric acids in stomach results in the pH of stomach to become acidic which range from 1.5 to 6.5 values.
What is the pH level of stomach?When the bolus enters the stomach, it aids the release of gastric juice having enzymes, mucous and HCL.
The upper and lower parts of stomach have varying pH values. Upper part has a pH of 4−6.5, while the lower part is with a pH of 1.5−4.0 which is highly acidic due to HCL.
Thus, the relative pH of stomach is acidic ranging from value 1.5 to 6.5.
