Why is each level of the energy pyramid smaller than the level directly below it?(1 point) Responses Because 10% of the energy at each level moves to the next level and some additional energy is converted to heat. Because 10% of the energy at each level moves to the next level and some additional energy is converted to heat. Because the sizes of each level show that 10% is consumed by organisms at that level. Because the sizes of each level show that 10% is consumed by organisms at that level. Because 90% of the energy is passed on to the next level to be used by the organisms there. Because 90% of the energy is passed on to the next level to be used by the organisms there. Because about 10% of the energy is converted to heat when organisms become ill and another 10% when they die.

Answer 1

Because 90% of the energy is passed on to the next level to be used by the organisms there.

Answer 2

The correct response is: Because 10% of the energy at each level moves to the next level and some additional energy is converted to heat.

Answer 3

The correct answer is: Because 10% of the energy at each level moves to the next level and some additional energy is converted to heat.

In an energy pyramid, each level represents a trophic level, which is a feeding level in an ecosystem. Energy flows through these trophic levels, starting from the producers (such as plants) and moving up to the consumers (such as herbivores, carnivores, and omnivores).

When energy is transferred from one trophic level to the next, only about 10% of the energy is passed on while the rest is lost as heat. This is due to the inefficient nature of energy transfer and the inefficiency of organisms in converting energy from one form to another.

So, at each trophic level, only a fraction of the energy from the level below is available for consumption and growth. As a result, the biomass (amount of living organisms) and energy decreases as you move up the energy pyramid. This explains why each level of the energy pyramid is smaller than the level directly below it.
