Question

multiple - choice question
what is ecological efficiency?
the amount of energy lost as heat from trophic level to trophic level
the amount of energy passed from trophic level to trophic level
the amount of light energy converted into chemical energy by photosynthesis
the rate at which energy is passed from trophic level to trophic level

Explanation:

Ecological efficiency is defined as the percentage of energy transferred from one trophic level to the next. It is about the rate of energy transfer between trophic levels. The first option is about energy loss as heat, the third option is about photosynthesis - specific energy conversion, and the second option is just about the amount of energy passed without considering the rate.

Answer:

The rate at which energy is passed from trophic level to trophic level
