EVERYDAY SCIENCE

Detailed explanation-1: -According to Lindeman’s 10% law, only 10% of energy is transferred to next level.

Detailed explanation-2: -At each step up the food chain, only 10 percent of the energy is passed on to the next level, while approximately 90 percent of the energy is lost as heat.

Detailed explanation-3: -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-4: -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-5: -The reason for this is that only around 10 per cent of the energy is passed on to the next trophic level. The rest of the energy passes out of the food chain in a number of ways: it is released as heat energy during respiration. it is used for life processes (eg movement)
