The fish is the first organism that would be tested and measured for DDT as it pass on the DDT to the upward trophic level in food chain. After that predators will be checked for DDT concentration.

Explanation:

DDT level in the organism gets increase as it moves upward in the trophic level.

Toxins as DDT gets incorporated to fats and tissues of the organism. It gets soluble in fats.

The highest concentration of DDT is observed in tertiary consumers as carnivore.

It can be seen that DDT concentration is more in producers than primary consumers. With the process of biomagnification the concentration of DDT increases at successive levels.

In aquatic food chain pesticides or heavy metals are consumed by aquatic organsims which are consumed by large birds and human. The DDT level will be checked in fish then birds and humans.
