Question

What is true of the energy that is passed from one trophic level to the next in a food chain? . . A)About 10% of the energy passed from one level to the next is released as heat.. . B)About 10% of the stored energy of one level becomes stored energy at the next higher level.. . C)The energy at each level increases by about 10% with each move up in trophic level.. . D)The total energy at all trophic levels is constant, but only about 10% is available for use by organisms for life functions.

Answer 1

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.

Answer 2

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.
