Which term indicates areas where water covers the soil for part of the year, providing important ecosystems for biodiversity?

• A. Wetlands
• B. Deforestation
• C. Desertification
• D. Agroecosystem

Answer: (A)

Wetlands are areas where water covers the soil for part of the year, creating a unique habitat that supports a wide variety of plants and animals. The constant or seasonal saturation leads to special soil conditions (hydric soils) and adaptations that foster rich biodiversity, along with important ecosystem services like flood control, water purification, and carbon storage. This defining feature—the water presence for part of the year—is why wetlands best fit the description. Deforestation means removing forests, not water coverage; desertification describes land becoming desert-like; and an agroecosystem refers to farming systems, not water-covered areas.
