Question

(a) State with reason the consequence of decrease in number of
carnivores in an ecosystem.
(b) In a food chain, state the

trophic level at which the concentration of
harmful chemicals is maximum. Why is it so ?​

Answer 1

Answer:

A. If the share of carnivores were to reduce in the ecosystem, then the herbivores would increase in number. This would lead to reduction in plant species as there would be more herbivores to eat them and thus it would create a huge mess of the ecosystem

B. As human occupy the top level of any food chain, the maximum concentration of chemicals is found in our bodies. This is called biological magnification.
