Question

If each level in a food chain typically loses 90 percent of the energy it takes in, and the producer level uses 1000 kcal of energy ,how much of that energy is left after the third trophic level

Answer 1

There is 10 kcal energy left in the 3rd trophic level.

Answer 2

The energy that is left after the third trophic level is 10 kcal.

How much of that energy is left after the third trophic level?

• The first trophic level uses 1000 kcal.
• The second trophic level used 100 kcal.
• So, the third trophic level uses 10 kcal leaving 1 kcal.
• The energy is transferred from trophic level to trophic level, and approximately 90% of it is lost each time.
• With some of it being lost as heat into the environment (as a result of respiration) and some being lost as partially digested food.

Hence, if each level in a food chain typically loses 90 percent of the energy it takes in, and the producer level uses 1000 kcal of energy, the energy that is left after the third trophic level is 10 kcal.
