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

Answer: (A)

Bioaccumulation is the buildup of a chemical inside an organism over time, especially when the substance is stored in fatty tissues and not readily eliminated. Because many lipophilic (fat-loving) contaminants persist and aren’t quickly excreted, their concentrations in the body rise with ongoing exposure, even if environmental levels are the same. This explains why waste ends up stored in fat tissue and accumulates over time. Biomagnification, by contrast, refers to increasing concentrations of a chemical as you move up the food chain, from prey to predator. Biodegradation is the breakdown of substances by microbes, and biotransformation is the body's metabolization of chemicals—often turning them into forms that are more water-soluble for excretion. These concepts describe processes that reduce or alter the chemical rather than accumulate it within an organism.
