According to the law, during the transfer of energy from one trophic level to another, only 10℅ is available for the next trophic level as the other 90℅ is lost as heat to the surroundings.

For example: In a given simple food chain-

Primary producer( Plants) ----> Primary consumer( deer) -------> Secondary consumer( Lion), the primary producers form the first trophic level, the primary consumers the second and so on. In this example, if the first level gets 1000kcal of energy, the next one gets 100 kcal while the third gets 10 kcal.

Exothermic reactions are those reactions in which heat is released. For eg. Carbon burns in oxygen to form carbon dioxide and heat energy is produced. C + O2 → CO2 + Heat Endothermic reactions are those reactions in which heat is absorbed. For eg.When nitrogen and oxygen are heated together to a particular temperature of about 3000oC, nitric oxide gas is formed. N2 + O2 + Heat → 2NO
