State 10% l

As we know that only 10% of energy is transferred from the first trophic level to the next and 90 % of the energy lost as heat to the surroundings. Let’s understand with an example.

Let's assume that the plants or producers have 10 joules of energy, according to 10 % law, only 1 joule of energy will be available for transfer to next trophic level that is herbivores (deer) and 10 % of 1 joule that is 1.1 joule of energy is available for the carnivores (lion).
