Statement I: Bioconcentration in humans can occur due to consumption of fish.

Statement II: Bioconcentration is the tendency of hazardous substances to accumulate in human tissues.

In the light of the above statements, choose the correct answer from the options given below:

Correct option is D

· Statement I is false because bioconcentration specifically refers to the direct uptake of contaminants from the environment (e.g., water) by an organism, not through consumption of other organisms. The process described in Statement I, where humans consume fish that have accumulated toxins, is called bioaccumulation, not bioconcentration.
· Statement II is true because bioconcentration indeed refers to the tendency of hazardous substances to accumulate in the tissues of living organisms, including humans, often from environmental exposure.
Information Booster: 1. Bioconcentration is the accumulation of substances from the environment (like water or soil) into an organism, without involving the food chain.
2. Bioaccumulation occurs when an organism accumulates substances by consuming other organisms (e.g., humans eating fish containing toxins).
3. Biomagnification refers to the increasing concentration of toxic substances as they move up the food chain, from prey to predator.
