Question

Answer the following questions on the basis of energy flow in an ecosystem.

a. Which form of the Sun's energy is trapped by the producers? To which form of energy is this energy trapped by the producers converted?

b. If the amount of energy stored by producers is 30000 KJ, calculate the energy received by the fourth trophic level.​

Answer 1

Answer:

a) Ans - The solar energy of the sun is trapped in the form of chemical energy by the process of photosynthesis.

b) Ans - 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.
