Question

flow of energy in trophic levels​

Answer 1

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.

Answer 2

Flow of energy through different trophic levels follows the 10% law.

The law states that when an predator eats the prey, the predator gains 10% of the energy from the prey.

Ex: Suppose a plant has 1000J of energy and a herbivores animal eats the said plant. That herbivores animal will receive 10% of the energy from the plant, i.e 1000 × $\frac{10}{100}$ = 100J

Now, when another carnivores animal eats the herbivore, it will receive the 10% of the energy from the herbivore, i.e 100 × $\frac{10}{100}$ = 10J

This is known as the 10% law
