What is the primary function of wetlands in the water cycle?

  1. Water storage

  2. Water filtration

  3. Water evaporation

  4. Water transportation


Correct Option: A
Explanation:

Wetlands act as natural sponges, absorbing and storing excess water, which helps prevent flooding and maintain stable water levels.

Which type of wetland is characterized by standing water and is often dominated by emergent vegetation?

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: C
Explanation:

Marshes are wetlands characterized by standing water and are often dominated by emergent vegetation such as reeds, sedges, and cattails.

What is the primary source of nutrients in bogs?

  1. Groundwater

  2. Surface water

  3. Atmospheric deposition

  4. Decomposition of organic matter


Correct Option: C
Explanation:

Bogs are ombrotrophic wetlands, meaning they receive most of their nutrients from atmospheric deposition, such as rain and snow.

Which type of wetland is characterized by a high water table and is often dominated by shrubs and trees?

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: D
Explanation:

Swamps are wetlands characterized by a high water table and are often dominated by shrubs and trees, such as cypress and tupelo.

What is the primary function of wetlands in flood control?

  1. Absorbing excess water

  2. Slowing down the flow of water

  3. Filtering pollutants from water

  4. Providing habitat for wildlife


Correct Option: A
Explanation:

Wetlands act as natural sponges, absorbing excess water during heavy rainfall or flooding, which helps reduce the risk of flooding downstream.

Which type of wetland is characterized by a low pH and is often dominated by sphagnum moss?

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: A
Explanation:

Bogs are wetlands characterized by a low pH and are often dominated by sphagnum moss, which creates a unique acidic environment.

What is the primary function of wetlands in water filtration?

  1. Removing pollutants from water

  2. Storing excess water

  3. Providing habitat for wildlife

  4. Slowing down the flow of water


Correct Option: A
Explanation:

Wetlands act as natural filters, removing pollutants and excess nutrients from water through various processes, such as sedimentation, absorption, and microbial activity.

Which type of wetland is characterized by a high water table and is often dominated by sedges and grasses?

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: B
Explanation:

Fens are wetlands characterized by a high water table and are often dominated by sedges and grasses, as well as various other plant species.

What is the primary function of wetlands in providing habitat for wildlife?

  1. Providing food and shelter for a variety of species

  2. Filtering pollutants from water

  3. Storing excess water

  4. Slowing down the flow of water


Correct Option: A
Explanation:

Wetlands provide important habitat for a wide variety of wildlife, including birds, fish, amphibians, reptiles, and mammals, by offering food, shelter, and breeding grounds.

Which type of wetland is characterized by a high water table and is often dominated by trees and shrubs?

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: D
Explanation:

Swamps are wetlands characterized by a high water table and are often dominated by trees and shrubs, such as cypress and tupelo.

What is the primary function of wetlands in carbon sequestration?

  1. Storing carbon dioxide from the atmosphere

  2. Releasing carbon dioxide into the atmosphere

  3. Absorbing methane from the atmosphere

  4. Releasing methane into the atmosphere


Correct Option: A
Explanation:

Wetlands play a significant role in carbon sequestration by storing carbon dioxide from the atmosphere in their soils and vegetation.

Which type of wetland is characterized by a low pH and is often dominated by ericaceous shrubs?

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: A
Explanation:

Bogs are wetlands characterized by a low pH and are often dominated by ericaceous shrubs, such as rhododendron and blueberry.

What is the primary function of wetlands in providing recreational opportunities?

  1. Providing opportunities for fishing, hunting, and birdwatching

  2. Filtering pollutants from water

  3. Storing excess water

  4. Slowing down the flow of water


Correct Option: A
Explanation:

Wetlands provide important recreational opportunities, such as fishing, hunting, birdwatching, and kayaking, which contribute to local economies and enhance the quality of life for communities.

Which type of wetland is characterized by a high water table and is often dominated by sedges and grasses?

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: B
Explanation:

Fens are wetlands characterized by a high water table and are often dominated by sedges and grasses, as well as various other plant species.

What is the primary function of wetlands in providing educational opportunities?

  1. Providing opportunities for learning about ecology and conservation

  2. Filtering pollutants from water

  3. Storing excess water

  4. Slowing down the flow of water


Correct Option: A
Explanation:

Wetlands provide valuable educational opportunities for students and the general public to learn about ecology, conservation, and the importance of protecting these unique ecosystems.
