In the following food chain, plants provide 500J of energy to rats. How much energy will be available to hawks from snakes?

Plants→Rats→Snakes→Hawks

Answer and Explanation:

The "rule of 10%" is the principle that controls the flow of energy through the food chain. Just 10% of the energy available at one trophic level is transferred to the following trophic level, according this law. 90% of the remaining energy is wasted as heat and through metabolic activities.

As a result, if the hawks have 50 J of energy accessible to them, the snakes must have had 500 J (10 times the hawks' energy), the rats must have had 5,000 J (10 times the snakes' energy), and the plants must have had 50,000 J. (10 times the amount of energy available to the rats).

Regarding the second half of your query, hawks are most likely the organisms with the highest concentration of pesticides in them due to their position at the top of the food chain and ability to consume a variety of organisms, including rats and snakes.

Because pesticides are difficult to break down in the environment and grow more concentrated as they go up the food chain, this process, known as biomagnification, takes place.
