When food energy passes from herbivores to carnivores,

Options

  1. ASome energy is increased
  2. BSome energy is decreased
  3. CRemain unchanged
  4. DNot relevant

Correct answer

B. Some energy is decreased

Step-by-step solution

The energy content is maximum in producers. The energy decreases at each trophic level of the food chain, as part of the energy is lost as heat and the major part of the energy is liberated during respiration for use in various activities. Only 10 % of the energy of the previous trophic level is received by the next trophic level, as proposed by 10 percent law of Lindeman (1942).
