What is one of the primary reasons for maintaining oak trees in their habitats?

1. They grow quickly

2. They support a wide range of species

3. They are commercially valuable

4. They are resistant to pests

The correct answer is: They support a wide range of species

Maintaining oak trees in their habitats is particularly important because they support a wide range of species. Oak trees are known to be keystone species in many ecosystems; they provide essential resources such as food and shelter for various organisms, including birds, mammals, insects, and fungi. The leaves, acorns, and fallen bark of oak trees offer nourishment to a multitude of species, thereby contributing to greater biodiversity within the ecosystem. This role is fundamental for the health of the ecosystem, as it ensures that numerous species can thrive in the habitat created by oak trees. In contrast to other factors, such as growth rate, commercial value, or pest resistance, the ecological support that oak trees provide is vital for sustaining wildlife and maintaining balanced ecosystems.
