Question

energy flow in a food chain is unidirectional justify and how pesticides enter into food chain and subsequently get into our body ​

Answer 1

Energy flow is always unidirectional because the energy from tertiary consumers are not transferred to the producers again.

nergy flow is always unidirectional because the energy from tertiary consumers are not transferred to the producers again.farmers use pesticides and fertilizers to the plants .they in turn are being absorbed by the the plants and passed on to the primary - secondary consumers so on .

nergy flow is always unidirectional because the energy from tertiary consumers are not transferred to the producers again.farmers use pesticides and fertilizers to the plants .they in turn are being absorbed by the the plants and passed on to the primary - secondary consumers so on .they are neither being metabolised nor excreted out of the bodies so is being passed on to the next organisms.
