Vedclass · Answer

(C) Biomagnification is the phenomenon of increasing concentration of a non-biodegradable compound in the tissues of organisms at successive trophic levels in a food chain,usually as a result of food intake.In this process,the concentration of the pollutant increases as we move up the trophic levels.The sequence of energy flow is: Producers $	o$ Primary consumers $	o$ Secondary consumers $	o$ Tertiary consumers $	o$ Top carnivores.In the given options,the grasshopper is a primary consumer,the toad is a secondary consumer,the cattle is a primary consumer,and the snake acts as a tertiary consumer.Since the snake occupies the highest trophic level among the given organisms,it will accumulate the highest concentration of $DDT$ due to biomagnification.

Which one of the following organisms is likely to show the highest concentration of $DDT$,once it has been introduced into the ecosystem?
