b)

Pesticides are chemicals used to control pests, such as insects, weeds, and fungi, in agricultural and other settings. While pesticides can be effective in controlling pests, they can also have negative effects on the ecosystem.

One of the primary effects of pesticides is their impact on non-target organisms, such as beneficial insects, birds, and mammals. Pesticides can kill or harm these organisms, which can disrupt food chains and webs and reduce biodiversity.

Pesticides can also enter the soil and water systems, where they can contaminate these resources and harm aquatic organisms. In addition, some pesticides can persist in the environment for long periods of time, leading to the accumulation of these chemicals in the food chain and potentially harming humans who consume contaminated food or water.
