Question

what is 10% rule and example for this​

Answer 1

Explanation:

According to the rule, only 10% of energy is transferred to the next level of food chain, out of the remaining 90%, some is used up metabolically for survival and the rest is lost as body heat. For example, if a plant receives 1000 J from Sun, the animal who eats that, say a cow, would only get 10 % of 1000 J or 100 J.

For example, the Sun releases 1000 J of energy, then plants take only 10 J of energy from sunlight; thereafter, a deer would take 1 J from the plant.
