The choice that is true of the energy that is passed from one trophic level to the next in a food chain is about 10% of the energy passed from one level to the next is released as heat. The correct answer is A.

The true statement of the energy that is passed from one trophic level to the next in a food chain is;

About 10% of the energy passed from one level to the next is released as heat

Further Explanation:

Trophic levels

  • Trophic levels refers to the food positions occupied by organisms in a food chain in a given ecosystem.
  • they include; producers which occupy the fisrt trophic level, primary consumer occupying second trophic level, etc.

Energy in trophic levels.

  • Energy is passed from lower to higher trophic levels up a food web or a food chain.
  • Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
  • Trophic level transfer efficiency measures the amount of energy that is transferred between trophic levels.
  • The amount of energy at each trophic level decreases as it moves through an ecosystem.
  • As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat or given off to the environment as heat.
  • The energy loss up the trophic levels explains why there are a few trophic levels in an ecosystem, normally four to five trophic levels, as there would be no enough energy to support extra trophic levels.
