Final answer:
Biomagnification is the term used to describe the process in which DDT concentration increases up the food chain.
Step-by-step explanation:
The phenomenon described in the question is called biomagnification. Biomagnification is the process by which certain substances, such as DDT, become increasingly concentrated at each trophic level in a food chain. This means that when a small animal consumes something with DDT, the DDT accumulates in its body. When a larger animal eats the small animal, it ingests a higher concentration of DDT. This process continues as we move up the food chain, resulting in higher levels of DDT in larger animals.
