Question

How much energy is available for the organisms of next trophic level?

• A. 10%
• B. 75%
• C. 1%
• D. 90%

Answer 1

The correct option is A

10%

The energy of sun is transferred from one trophic level to another i.e. from plants to herbivores to small carnivores and then to large carnivores. Plants are able to trap only 1% of energy of sun and later on only 10% of this are available for organism of next trophic level. This law of 10% availability of energy will apply for each trophic level.
