Answer 1

T4
bcos DDT increases with increasing tropic level.

Answer 2

Answer:

In trophic level T4 , chemicals like DDT are accumulated in highest concentration. As these chemicals are not biodegradable they get accumulated progressively at each trophic level. As carnivores or human beings occupy the top level in any food chain, the maximum concentration of these chemicals get accumulated into their bodies.
