Which of the following is one way that humans can protect biodiversity?

A.
understanding and protecting habitats

B.
using large-scale single-crop agriculture

C.
encouraging deforestation in fire-prone areas

D.
introducing nonnative plants to an ecosystem

A. understanding and protecting habitats

The correct answer is A. Understanding and protecting habitats.

The correct answer is A. Understanding and protecting habitats.

To arrive at this answer, we need to understand what biodiversity is and how it can be protected. Biodiversity refers to the variety of life on Earth, including all plants, animals, and ecosystems. Protecting biodiversity is crucial because it ensures the balance and stability of ecosystems, as well as several benefits for human well-being.

Now, let's break down the other answer options and explain why they are not effective ways to protect biodiversity:

B. Using large-scale single-crop agriculture: Large-scale single-crop agriculture, also known as monoculture, involves growing a single type of crop over a large area. While this method may be efficient for food production, it can have negative impacts on biodiversity. Monocultures often lead to the loss of native plants and the associated species that rely on them, reducing overall biodiversity.

C. Encouraging deforestation in fire-prone areas: Deforestation, especially in fire-prone areas, can have detrimental effects on biodiversity. Forests are home to countless species and provide important habitats for wildlife. Encouraging deforestation would result in the loss of these habitats, leading to the decline or extinction of many species.

D. Introducing nonnative plants to an ecosystem: Introducing nonnative plants to an ecosystem can disrupt the balance of native species and negatively impact biodiversity. Nonnative plants may outcompete native species, reduce available resources, and alter the structure of ecosystems, leading to the decline of native plants and the animals that depend on them.

In conclusion, understanding and protecting habitats is the recommended approach to protect biodiversity. This involves preserving natural areas, supporting conservation efforts, and ensuring that ecosystems are intact and functioning properly.
