Question

In a food web, what happens as energy transfers through different trophic levels?

A) Energy increases as it moves up trophic levels.
B) Energy decreases as it moves up trophic levels.
C) Energy remains constant as it moves through trophic levels.
D) Energy flows in the opposite direction in a food web.

Answer 1

In a food web, energy decreases as it moves up trophic levels.

Step-by-step explanation:

In a food web, energy decreases as it moves up trophic levels. This means that there is less energy available for organisms at higher trophic levels compared to lower trophic levels.

The reason for this decrease in energy is that each trophic level loses energy through metabolic processes and heat loss. Only about 10% of the energy from one level is available to the next level, resulting in a decline in energy from lower to higher trophic levels.
