NEET BIOLOGY

Detailed explanation-1: -Biomagnification is a process by which contaminant concentrations increase in the tissue of higher species of the food chain. As contaminated smaller organisms are consumed, chemicals are accumulated and magnified in the tissue and organs of larger animals.

Detailed explanation-2: -Biomagnification is the process by which toxic chemicals build up within predators. This typically occurs across an entire food chain and affects all of the organisms but animals higher up in the chain are more impacted.

Detailed explanation-3: -Biomagnification is the accumulation of a chemical by an organism from water and food exposure that results in a concentration that is greater than would have resulted from water exposure only and thus greater than expected from equilibrium.

Detailed explanation-4: -The higher an animal is on the food chain (e.g. tertiary consumer such as seals), the greater the concentration of DDT in their body as a result of a process called biomagnification.

Detailed explanation-5: -Biomagnification is a process causing the concentration of a substance (crosses) to increase at higher levels of the food chain. In this scenario, a pond has been contaminated with toxic waste. Further up the food chain, the concentration of the contaminant increases, sometimes resulting in the top consumer dying.
