EVERYDAY SCIENCE

Detailed explanation-1: -On average, only about 10% of the energy stored as biomass in one trophic level (e.g., primary producers) gets stored as biomass in the next trophic level (e.g., primary consumers). Put another way, net productivity usually drops by a factor of ten from one trophic level to the next.

Detailed explanation-2: -Secondary consumers receive 10% of the energy available at the primary consumer level (1% of the original energy).

Detailed explanation-3: -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-4: -Hence, only 10% of energy is transferred from the producer level to the successive trophic levels.

Detailed explanation-5: -Only about 10% of the energy is transferred from one trophic level to another. The rest is used for life processes of the organism and some is lost as heat.
