Answer 1

(i) Producers is the first tropic level of the terrestrial food chains. Generally organisms at the lowest tropic level are always greater in number. As we move to the higher tropic levels, the number and the complexity of organisms increases. This helps to maintain the balance in the ecosystem. If there would have less producers compared to primary consumers, they would have staved and further food chain would be disturbed. Also, the amount of energy transferred from one tropic level to the other is less (10%). Hence, it is important that a larger population exist for a lower tropic level than that found above it.

(ii) The level of biological magnification is different at different levels of the ecosystem. It will be maximum at the higher tropic level and minimum at the lowest tropic levels.
Example:- In humans, Biological magnification is the most.
