If 1000 units of energy are available at the producer level of the energy pyramid, about how many units are available for first-level consumers? Second-level consumers? Third-level consumers?
Answer:
The next level after the producer would receive 100 units of energy.
Explanation:
The amount of energy that passes on to the next level is only 10%.
If the producers start with 1000 units, only 10% passes on. The next trophic level would have 100 units, the next after that would have 10, and so on. Only 10% of the energy is passed on into the next level.
The Majority of the untied states resides in what atmospheric convection area
Answer:
Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere. Convective currents of air in the atmosphere are referred to as updrafts and downdrafts. In addition to heat transfer, convention can be driven by other properties (e.g., salinity, density, etc)
Explanation:
Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere.
What do you mean by convection?Convection is the process of losing heat through the movement of air or water molecules across the skin. The use of a fan to cool off the body is one example of convection.
Convection currents are present in the air– A good example of convection current is the warm air that rises towards the ceiling in your house. The process happens as the warm air is said to be less dense than that of the colder air.
The best description of a convection current is that e. it is the process in which warm material expands and rises while cool material contracts and falls.. Convection current in the atmosphere causes warm air to rise up from the surface.

There would be no ocean life without _____?
1.marine snow
2.phytoplankton
3.thermocline
4.runoff
Answer:
phytoplankton
Explanation:
they are the base of the food web, without them other large organisms will die.
There would be no ocean life without phytoplankton, hence option 2 is correct.
What is phytoplankton?Without plankton, the bigger creatures in the marine food web would likely perish. Millions of people would be hungry if there were no plankton or fish.
Millions, if not billions, of people, would be hungry if the oceans were to disappear. The foundation of the food chain and the basis of all ocean life is phytoplankton.
Fish and other big creatures eat phytoplanktons, which also provide them with energy. They depend on light or the sun to survive.
Without it, we'd be lost, but we hardly even notice it. The small plants and creatures that live in our seas, lakes, and ponds, known as plankton, are essential to the existence of the earth.
Therefore, the food chain and the basis of all ocean life are phytoplankton.

Which of the following components of an ecosystem are not abiotic factors?
A. fallen leaves
B. wind
C. small rocks
D. sunlight
Abiotic components are the non-living, chemical, and physical elements of an ecosystem that have an impact on living things and how ecosystems function, hence option A. fallen leaves is the correct option.
What are abiotic factors in the ecosystem?Temperature, light, water, and other abiotic elements of the ecosystem are examples.
The nonliving components of the environment, or abiotic influences, frequently have a significant impact on living things. Water, sunlight, oxygen, soil, and temperature are examples of abiotic variables.
Abiotic factors are non-living components of an ecosystem that influence their surroundings. Examples could be light, water, and temperature in a terrestrial habitat.
Therefore, abiotic elements in a marine ecosystem would be salinity and ocean currents. A particular ecosystem is produced by the interaction of biotic and abiotic elements.

Why would a change in brain size be important for the evolution of hominids as opposed to other species? (Think beyond a ‘big brain means they are smarter.’ What can you do with your brain that other organisms may not be able to?)
Answer:
Bigger brain helped our ancestor survives.
Explanation:
Change in brain size is very important for the evolution of hominids as opposed to other species because bigger brain helped our ancestor survives when the environmental conditions changed with the passage of time. They use their brain to avoid negative effects of environment change. I do a lot of things with my brain that other organisms may not be able to do that such as inventions of new technologies.

what makes living things and non-living things successful in their attempts to take flight?
Answer:
Any living or non-living thing trying to take flight will have two forces working against them: gravity and drag. Gravity is the force that the Earth exerts on all things pulling them back towards its centre. ... Birds also have two forces that help them in their attempts to take flight.
Explanation:
If living things and non-living things have the ability to work and resist two forces which are gravity, and drag. They will take a successful attempt in their flight.
What do you mean by Living things?Living things may be defined as creatures that have a variety of characteristics that are displayed to different degrees: they respire, move, respond to stimuli, reproduce, etc.
Birds also resist these two forces. And take a successful attempt of flight. The air resists the motion of the bird and the resistance force, is called drag. Gravity is the downward acting force that is mediated by the earth's surface.

Explain how natural processes, like earthquakes, unearth new rock layers and fossil
Answer:
Earthquakes shake Earth, sometimes causing cracks. When Earth shakes, it moves the crust around and this could help expose new rock layers and fossils.
The study of a living being is called biology.
Earthquake is defined as any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks.
When an earthquake occurs it moves the tectonic plate and it will lead to the formation of a new place. sometimes it cracks the earth's surface which will show up what is inside it.
The study of that cracks leads to unearthing the new fossils.
The biggest crack in the earth is a marine trench.

What do you notice about the path oxygen
molecules take inside the Metabolism Simulation of
a healthy body? Describe in detail.
Answer: something that i notice about the path oxygen is that anytime i eat something oxegen comes in and then after that the remaining oxegen comes out and then the lefover oxegen stay inside the respiratory system
Explanation:
The path oxygen takes inside the metabolism simulation is ; Diffusion
When we breathe in air the oxygen molecules contained in the air we breathe in move inside into our capillaries and from the capillaries into the body cells of an individual through a specific pathway known as diffusion.
As the oxygen moves into the the body cells from the capillaries the carbon dioxide ( by product ) contained in the body cells moves into the capillaries and is expelled out through the lungs.
Hence we can conclude that the path oxygen takes inside the metabolism simulation is diffusion.

Force can cause a moving object to stop movi
Answer:
6. True
7. False
8. True
9. False
10. True
Explanation:
The force of gravity acting on an object is measured by weight because weight is also refers to the force having gravity instead of acceleration. In the examples i. e. friction and gravity are types of force but velocity is not a force, it refers to speed of an object. If both forces having same magnitude but opposite in direction then both forces cancel their effect and the object remain stationary. No, length of a force arrow does not represent the direction of the force, it represents magnitude of a force. Yes, force can stop or tend to stop a moving object and move or tend to move a stationary object.
Which side or sides of the box have the same dimensions as those of a cross section parallel to side AEHD
Answer:
Sides AEHD and BFGC have the same dimensions as a cross section parallel to side AEHD.
Explanation:
Sides AEHD and BFGC have the same dimensions as a cross section parallel to side AEHD.
Answer:
part A : Sides A-E-H-D and B-F-G-C have the same dimensions as a cross section parallel to side A-E-H-D
part B: The length of the side is 3 inches, and the width of the side is 3 inches.
The perimeter can be found using this formula:
perimeter
=
2(length + width)
=
2(3 + 3)
=
2(6)
=
12 inches.
Part C:The dimensions of a cross section that is parallel to side AEHD are the same as those of side A-E-H-D. So the perimeter of a parallel cross section is the same as the perimeter of side A-E-H-D, or 12 inches.
part D: The cross section that passes through the points A, F, G, and D is the rectangle A-F-G-D.
A-F = D-G = 5 inches
A-D = G-F = 3 inches
PART E: F = D-G = 5 inches
AD = G-F = 3 inches
area of rectangle A-F-G-D
=
length × width
=
5 inches × 3 inches
=
15 square inches
