Which of the following is NOT a function of wetlands in the environment?

• A. Limits biodiversity
• B. Filters pollutants
• C. Provides habitat for wildlife
• D. Stores floodwaters

Answer: (A)

Wetlands support a range of ecological services that boost the environment rather than diminish it. They provide varied habitats—marshes, swamps, and bogs—that support many kinds of plants and animals, creating diverse ecosystems and rich biodiversity. They also act as natural filters, with plants and soils removing pollutants and trapping sediments as water moves through. Additionally, wetlands absorb excess rainfall and release it slowly, helping to store floodwaters and reduce flood impacts downstream. Because of these roles, the statements describing filtering pollutants, providing habitat for wildlife, and storing floodwaters are true functions of wetlands. The idea that wetlands limit biodiversity is not a function they perform; in fact, wetlands tend to enhance biodiversity.
