Question

An analysis of soil sample revealed $0.1mg$ of a pesticide and $1mg$ of the same of pesticide was found in grains. However in the adipose tissue of birds the concentration was $2mg$. The reason for this is the phenomenon known as

• A. Bioabsorption
• B. Biotranslocation
• C. Biomagnification
• D. Biomulitiplication

Answer 1

The correct option is C Biomagnification

Biomagnification is the accumulation or increasing bioconcentration of lipophilic pesticides in the top members of the food chain. During biomagnification, the concentration of pesticides goes on increasing according to the food chain and highest values occur in the consumers of the top trophic level. So, the value of pesticide will go on increasing from the soil, to the plant and to the bird.

Thus, the correct answer is option C.
