Q 30(1+1+1)
If a harmful chemical enters a food chain comprising peacock, snake,mice and plants.

b) Which of these organism is likely to have maximum energy available for transfer to next level
Why?
​

Answer 1

Answer:

According to the process of biomagnification, toxins increase in each successive higher member of food chain. Since the peacock is at the apex of the food-chain it will have the maximum concentration of toxins. Hope it helps and have a nice day!

Answer 2

Plants will have maximum energy available for transfer to next level. Reason is as follows -

• As per 10% rule, only 10% of energy gets transferred from one trophic level to another. Since plants are at the lowest level and producers, they have the maximum amount of energy.

• The concentration of harmful chemical will be maximum in peacock, as it belongs to the topmost trophic level. The concept is defined by biomagnification, where non biodegradable harmful chemicals increase at every trophic level.
