LIFE SCIENCE

Detailed explanation-1: -As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller. While energy can not be created or destroyed is it released as heat within each level. Approximately only 10% of energy is passed from one level to the next.

Detailed explanation-2: -The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Detailed explanation-3: -With less energy at higher trophic levels, there are usually fewer organisms a s well . Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass.

Detailed explanation-4: -The transfer of energy from the lower level to the higher trophic level is called. A Food chain.
