Question

The following statement is true or false:

Only 10 per cent of the light energy given by the sun is available for transfer at each higher trophic level in a food chain.

Answer 1

False. 

Explanation:

Only about 1% of the solar energy falling on plants is captured by autotrophs (green plants) through photosynthesis. Of the energy stored at one trophic level, only about 10% is transferred to the next trophic level.

Therefore, 10% refers to the transfer of energy from one trophic level to the next, not to the solar energy received from the Sun.
