What are accumulative pesticides known for?

Decomposing quickly in the environment
Building up in the bodies of animals
Breaking down under UV light
Being non-toxic to wildlife

The correct answer is: Building up in the bodies of animals

Accumulated pesticides are characterized by their ability to build up in the bodies of animals over time. This accumulation occurs because these substances are not easily broken down or excreted by the biological systems of living organisms. As a result, they can concentrate in the fatty tissues of animals, leading to potentially harmful effects on health and ecosystems over time. This characteristic can lead to bioaccumulation, which is the increase in concentration of a substance in the tissues of living organisms as they consume contaminated food or water. The other options describe behaviors or properties of pesticides that do not align with the concept of accumulation. For instance, the quick decomposition of certain pesticides in the environment signifies a lower risk of bioaccumulation. Similarly, pesticides that break down under UV light do not pose the same risk of building up in animal tissues. Non-toxic pesticides would not typically cause accumulation in bodies because they do not have the same persistence or harmful effects associated with cumulative pesticides.
