What happens during biomagnification?

During biomagnification, the concentration of toxins increases at higher trophic levels within an ecosystem. This phenomenon occurs because toxins that are persistent, such as heavy metals or certain pesticides, are not easily broken down or excreted by organisms. As one organism consumes another, it accumulates the toxins present in its prey. Since larger predators eat many smaller prey, the toxins accumulate in their bodies over time, often leading to much higher concentrations than those found in the plants or animals lower in the food chain.

This process creates significant health risks for top predators, including humans, who may experience adverse effects from the high levels of toxins accumulated in their systems. Understanding biomagnification is crucial for environmental protection and wildlife conservation, as it underscores how pollutants can have far-reaching impacts on ecosystems and food webs.
