Question

If a harmful chemical enters a food chain comprising peacock, snake, mice and plants. a) Which of these organisms is likely to have maximum concentration of the chemical in its body ? Why ?
b) Which of these organism is likely to have maximum energy available for transfer to next level ? Why ?
c) Why a food chain shouldn’t be of more than five tropic level ?

Answer 1

Answer:

1. 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.

2. In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy. The energy in each trophic level of an energy pyramid is just 10 percent of the energy in the level below it.

3.Energy is passed up a food chain or web from lower to higher trophic levels. ... This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. Sometimes there may be a fifth trophic level, but usually there's not enough energy left to support any additional levels.
