What happens when a pesticide is added to a food chain?

When a pesticide is added to a food chain, it can disrupt the balance of the ecosystem by affecting non-target organisms, including beneficial insects and wildlife. As the pesticide is absorbed and accumulated through the food chain, it can lead to bioaccumulation and biomagnification, where higher concentrations of the chemical are found in predators at the top of the food chain. This can result in harmful effects on animal health, reproductive issues, and even population declines. Additionally, the pesticide can contaminate soil and water sources, further impacting biodiversity and ecosystem health.
