Question

Why is each level of the energy pyramid smaller than the level directly below it?(1 point)
Responses

Because about 10% of the energy is converted to heat when organisms become ill and another 10% when they die.
Because about 10% of the energy is converted to heat when organisms become ill and another 10% when they die.

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.

Answer 1

Because 10% of the energy at each level moves to the next level and most of the rest is lost (as heat, metabolism, waste), each successive level has less available energy.
