How does inefficient transfer of energy among trophic levels result in the typically high endangerment status of many top predators?
A)Top-level predators are destined to have small populations that are sparsely distributed.
B)Predators have relatively large population sizes.
C)Predators are more disease-prone than animals at lower trophic levels.
D)Predators have short life spans and short reproductive periods.
E)A, B C, and D are all correct.

Question

Quizplus · Accepted Answer

Inefficient transfer of energy among trophic levels means that there is less energy available for predators at the top of the food chain. This makes it difficult for them to maintain their populations and can result in small populations that are widely distributed, making them more vulnerable to extinction. This is why top predators are typically endangered or threatened species. Factors such as disease-proneness, short lifespans and reproductive periods may also contribute to their endangerment, but the primary reason is the inefficient transfer of energy. Therefore, option A is the best choice.
