Answer 2

BONJOUR DEAR!

Decreases . Energy is transferred from the sun to the primary producers, primary consumers, secondary and tertiary consumers. Although, not all energy is passed along through the trophic levels. Energy may be dumped off in any stage of the cycle, either to start back up in a new cycle, or to be lost from the ecological cycle forever. Energy is lost through: . Cell respiration . Feces and other waste . Unconsumed organic material (teeth, nails, fur, etc.) . Release of heat into the atmosphere . Due to the loss of energy throughout the various natural processes, only about 5-20% of energy is transferred to one trophic level to the next (depending on the ecosystem), meaning 80-95% of it is lost. If only 10% of energy was transferred, then 1% of the energy the primary producers contained was transferred to the secondary consumers. This is the reason almost all food chains (few exceptions) consist of a population of low-level organisms that is larger than the population its consumers.
