Question

energy flow in ecosystem is unidirectional justify?Explain how the pesticides enter a food chain and subsequently get into our body,name this processes

Answer 1

Answer:

according to the law of 10% law of energy transfer only 10% of total energy is transfer to the next organism in a food chain and it is not bidirectional.

the process is called biomagnification

Answer 2

Explanation:

The food which is produced by the plants that we can eat contains many healthy things which can improve our immune system. These things which are healthy are transferred from that grown fruit or vegetables to our body. These can never revert back as the food which we have consumed cannot be obtained back. Hence,this flow of energy in the ecosystem is unidirectional as it does not revert back and this process is called biological magnification. The processed food is not degradable and gets accumulated at each trophic level
