Question

Suppose the amount of energy available to caterpillar in a terrestrial food chain is 250 KJ. What will be the energy at 1st trophic level and 4th trophic level in the given food chain and why ? Plant --> caterpillar --> mouse --> snake

Answer 1

Answer:

5000 KJ

Explanation:

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.
