The fraction of energy lost when an organism proceeds from one trophic level to the next trophic level is

Options

  1. A10 percent
  2. B20 percent
  3. C30 percent
  4. D90 percent

Correct answer

D. 90 percent

In a typical food chain, only ten percent of the energy is passed to the next consumer in the unidirectional manner and 90% is lost to the environment as heat. In a typical food chain, the apex predator receives the least amount of energy and hence, a single food chain typically does not ha
