Questions: Nonnative species disrupt the natural variability of an ecosystem. Please select the best answer from the choices provided T F

The answer is T (True): Nonnative species disrupt the natural variability of an ecosystem.

Explanation:

• Nonnative species, also known as invasive species, are organisms that are introduced to an ecosystem where they do not naturally occur. These species can disrupt the natural variability and balance of ecosystems by outcompeting native species for resources, altering habitats, and sometimes introducing diseases.
• The introduction of nonnative species often leads to a reduction in biodiversity, changes in species composition, and can have cascading effects on the ecosystem's structure and function.
• Therefore, the statement that nonnative species disrupt the natural variability of an ecosystem is true.
