Question

Of the total amount of energy that passes from one trophic level to another, about 10% is

• A. Respired and becomes heat
• B. Passed out as faeces or urine
• C. Stored in the body
• D. Recycled to autotrophs

Answer 1

The correct option is C Stored in the body

The trophic level of an organism is the position it occupies in a food chain. When green plants are eaten by primary consumers, a great deal of energy is lost as heat to the environment, some amount goes into digestion and in doing work and the rest goes towards growth and reproduction. An average of 10% of the food eaten is stored in its own body and made available for the next level of consumers.

So, the correct option is option C.
