Question

the limits for the number of trophic levels in a food chain

Answer 1

Decrease in energy at higher trophic levels limits the number of trophic levels in a food chain. When the number of links keep increasing, the amount of energy available decreases, as only 10% of energy gets transferred from one trophic level to the next.

Answer 2

The decrease in energy with the higher trophic level limits the number of trophic levels in the food chain or food energy pyramid.

Explanation:

• The plants are at the lower most trophic level and are the highest source of energy the energy from the plants are transfer to the consumers by 10%.
• At each successive trophic level the 10% of energy is passed. This is in accordance with the 10% law.
• Thus the energy reaching from the lower to the higher trophic levels decreases considerably and the highest trophic level acquires the lowest energy.
