Question

The deposition of pesticides in fatty tissue of the organisms is called ............

• A. Biomagnification
• B. Bioaccumulation
• C. Bioconcentration
• D. Biodegradation

Hint:

Bioaccumulation occurs within an organism; biomagnification occurs across food chains.

Answer 1

The Correct Option is B

Step 1: Understanding the concept.
Bioaccumulation refers to the gradual buildup of toxic substances like pesticides in the body tissues of an organism over time.
Step 2: Role of fatty tissues.
Many pesticides are fat-soluble and get stored in fatty tissues instead of being excreted, leading to accumulation.
Step 3: Differentiating related terms.
Biomagnification refers to increase in concentration across trophic levels, while bioconcentration refers to uptake directly from environment.
Step 4: Final conclusion.
Thus, deposition of pesticides in fatty tissues is correctly termed bioaccumulation.
