Question

ducers make 10,000 kcal of energy.
he best two options that explains what happens to this energy as it is passed from one trophic level to the next.
each trophic level, organisms have identical structures for energy storage.
e total energy available at each trophic level increases because organisms at higher levels eat those at lower levels.
ergy is lost at every level in the form of biomass.
ergy is lost at every trophic level in the form of heat.
rtng from producers, the energy received by each subsequent trophic level decreases by 90 percent.
e percent of energy transferred to the next level is 100% for every organism.

Explanation:

Step1: Analyze energy transfer in trophic levels

In an ecosystem, when energy is passed from one trophic level to the next, only about 10% of the energy is transferred to the next level. This is known as the 10% rule. The rest of the energy is lost.

Step2: Consider energy loss forms

Energy is lost at every trophic level. One of the main forms of energy loss is in the form of heat due to metabolic processes like respiration. Also, based on the 10% rule, starting from producers, the energy received by each subsequent trophic level decreases by 90 percent (since 10% is transferred, so 1 - 0.1=0.9 or 90% is lost).

Answer:

Energy is lost at every trophic level in the form of heat. Starting from producers, the energy received by each subsequent trophic level decreases by 90 percent.
