Question

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

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

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

C) Because the sizes of each level show that 10% is consumed by organisms at that level.

D) Because 10% of the energy at each level moves to the next level and some additional energy is converted to heat.

Answer 1

D) Because only about 10% of the energy at each level moves to the next level and the rest is lost (mainly as heat and waste) during metabolism.
