Living Environment Regents Practice Test

What is one negative effect of using native grasslands for farming?

1. Increased biodiversity among species.

2. Enhanced soil quality over time.

3. Less biodiversity in the ecosystem.

4. Higher levels of carbon sequestration.

The correct answer is: Less biodiversity in the ecosystem.

Using native grasslands for farming can lead to less biodiversity in the ecosystem primarily because of the transformation of a natural habitat into an agricultural space. Native grasslands typically host a wide range of species, including various plants, insects, and animals, which thrive in the unique environmental conditions of these habitats. When these areas are converted for agricultural use, it often results in monoculture practices—growing a single crop over large areas. This shift can disrupt the natural balance of the ecosystem, as it often eliminates the native plant species that support diverse animal populations and microorganisms. The reduction in habitat complexity can lead to a decline in species that rely on native plants for food and shelter, ultimately resulting in decreased overall biodiversity. Therefore, while farming can provide benefits such as increased food production, the loss of biodiversity can have long-lasting negative impacts on ecosystem health and resilience.
