Question

1. what is a key role of wetlands like the everglades?

a. producing crops
b. logging
c. water purification
d. providing shelter for bison

Explanation:

• Option a: Wetlands like the Everglades are not primarily used for crop production as their ecosystem is not suitable for large - scale agriculture.
• Option b: Logging is related to forests, not wetlands. Wetlands do not have a significant role in logging.
• Option c: Wetlands play a crucial role in water purification. They filter out pollutants, excess nutrients, and sediments from water as it flows through the wetland ecosystem. For example, plants in the wetland can absorb nutrients like nitrogen and phosphorus, and the soil and organic matter can trap sediments and some pollutants.
• Option d: Bison are more associated with grasslands and prairies, not wetlands like the Everglades. The Everglades' wildlife is more adapted to wetland conditions, such as alligators, various bird species, etc.

Answer:

c. Water purification
