Describe how the available energy may affect the population sizes of organisms at different trophic levels.

Higher trophic level animal populations will be smaller than lower trophic level animal populations when the energy available at each trophic level declines.

The pace of population increase depends on the amount of energy accessible to it. Population dynamics are also influenced by other density-independent and density-dependent factors, such as biotic interactions.

Energy decreases as it moves up the food chain because it is lost as metabolic heat when animals from one trophic level are consumed by those from the next level.

All trophic levels may die out, upsetting the balance of that ecosystem, also known as homeostasis, if one trophic level's population increases or decreases too much.

Therefore, Energy transmission between trophic levels is quantified by trophic level transfer efficiency (TLTE).
