What term describes a pesticide that builds up in animals and plant tissues?

1. Persistent

2. Accumulative

3. Beneficial

4. Volatile

The correct answer is: Accumulative

The correct term to describe a pesticide that builds up in animals and plant tissues is accumulative. This term refers to substances that can be stored in the tissues of organisms over time, leading to increased concentrations with continued exposure. In the context of pesticide use, accumulative substances can pose significant ecological and health risks, as they may not only remain in the environment but also potentially affect the food chain, with organisms higher up the chain accumulating higher concentrations of the pesticide. Persistent, while related, typically refers to the length of time a pesticide remains active in the environment rather than its ability to accumulate in tissues. Beneficial describes pesticides or substances that have positive effects, often referring to those that control pests without harming beneficial organisms. Volatile refers to how easily a substance can evaporate at room temperature, which is not related to tissue buildup. Understanding these distinctions is essential for effective pest control and environmental protection strategies.
