Why is so little of the energy from one trophic level transferred up to the next trophic level?

Answer 1

All of the energy that enters an organism is not available to the next trophic level. This is because while the organism has the energy they use most of the energy up before the next level eats that level.

Answer 2

Because the animal uses so much of the energy it only saves a little bit and that's the energy we get from food

Answer 3

Most of the energy is used up by the predator

Answer 4

This is because organisms use much of the energy that they consume for life processes, such as respiration, movement, and reproduction.

Answer 5

Because every organism, upon consuming a resource, must expend some energy in order to digest/process that resource. Thus not all energy is passed from trophic level to trophic level.

Answer 6

because by eating a whole animal you only receive 10% of its energy. the other 90% goes to living the animals life

Answer 7

Because energy is used by the prey through movement, respiration and growth so that by the time the predator eats the animal little energy remains.

Answer 8

because only some part is passed on in the form of food to next trophic level
