Question

(b) Analyse the food chain given below and find the amount of energy received by the
organism in third trophic level. (Given: Amount of energy in the producers i.e.
grass=30000 J) Grass →Rabbit→ Snake →Eagle

Answer 1

Answer:

In an ecosystem, along with the food chain, there is a loss of energy and only 10 percent of the energy available at each trophic level is passed on to the next trophic level. Thus, if originally 5000 KJ of energy is available, at the next (or second) trophic level 500 KJ of energy will be available, at the next (or third) trophic level 50 KJ of energy will be available, at the next (or fourth) trophic level 5 KJ of energy will be available.

Therefore, the correct answer is option D
