Question

What will be the amount of energy available to the organisms of the 2nd trophic level of a food chain, if the energy available at the first trophic level is 10,000 joules?(All India - 2015)

Answer 1

As we know that, only 10% of the total energy is transferred from one trophic level to another. So, The amount of energy available to the organism of the 2nd trophic level of a food chain, will be 10% of 10,000 Joules which can be calculated as follows:

transferred from one trophic level to another. So, The amount of energy available to the organism of the 2nd trophic level of a food chain, will be 10% of 10,000 Joules which can be calculated as follows: Energy available to the organisms in 2nd trophic level = 10% of 10000 J = 10\100 X 10000 Therefore, 1000 Joules of energy will be transferred from first trophic level to second trophic level.
