What is biological magnification? Will the levels of this magnification be different at different levels of the ecosystem?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Biological Magnification**:
Biological magnification, also known as biomagnification, refers to the process where harmful chemicals, such as pesticides or heavy metals, accumulate in the tissues of living organisms. This accumulation happens as these organisms are consumed by others in a food chain.

2. **Accumulation in Trophic Levels**:
In a food chain, different organisms occupy different trophic levels. For example, phytoplankton (primary producers) are eaten by zooplankton (primary consumers), which are then consumed by small fish (secondary consumers), and finally, larger fish (tertiary consumers) eat the small fish. As you move up the food chain, the concentration of harmful chemicals increases.
