Question

energy flowing in a food chain is uni directions directions explain​

Answer 1

Answer:

This literally means that the change in form of energy is one in one direction.

Like, the plants use solar energy to produce chemical energy. That chemical energy can only be utilized either by the plant itself or another herbivore, but it never be again converted to solar energy.

So we conclude that energy change can never be reverted or reversed.

PLEASE MARK AS BRAINLIEST....!!!!

Answer 2

Answer:

The flow of energy in ecosystem is said to be unidirectional because energy lost as heat from living organisms of a food chain can't be reused by plants in photosynthesis.

During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path

*Energy is trapped by producers.(from the sun)

This energy cannot be reverted back to the sun.

It steadily goes to the next tropic level. And thus energy flows constantly in only one direction.Thus,unidirectional.

Also,biological magnification is how pesticides enter human body.

That is, harmful chemical like pesticides get mixed with water or soil.Since they are non biodegradable;they get concentrated and accumulated in every trophic level.The tertiary consumers being humans get the most amount of pesticides.
