Biomagnification happens when toxic chemicals, like DDT, whose remains in the environment are consumed indirectly by organisms through food. These get transferred from lower trophic levels to higher trophic levels within a food web, resulting in a higher concentration in apex predators. When an organism in the higher food chain consumes the lower organism containing such chemicals, the chemicals can get accumulated in the higher organism. Bioaccumulation takes place in a single organism over the span of its life, resulting in a higher concentration in older individuals. It is the gradual accumulation of a certain chemical into the living tissue of an organism from its environment. This accumulation may result from direct absorption from the environment or from ingestion of food particles. The presentation can equip you with more details.
