Which of the following is NOT a primary ecological function of wetlands?

  1. Flood control

  2. Water filtration

  3. Carbon sequestration

  4. Habitat provision


Correct Option: C
Explanation:

Carbon sequestration is not a primary ecological function of wetlands. Wetlands primarily function in flood control, water filtration, and habitat provision.

Wetlands help control floods by:

  1. Absorbing excess water

  2. Releasing water slowly

  3. Creating natural levees

  4. All of the above


Correct Option: D
Explanation:

Wetlands help control floods by absorbing excess water, releasing water slowly, and creating natural levees.

Wetlands help filter water by:

  1. Trapping sediment and pollutants

  2. Releasing oxygen into the water

  3. Providing habitat for aquatic plants

  4. All of the above


Correct Option: D
Explanation:

Wetlands help filter water by trapping sediment and pollutants, releasing oxygen into the water, and providing habitat for aquatic plants.

Wetlands provide habitat for a variety of organisms, including:

  1. Fish

  2. Birds

  3. Amphibians

  4. All of the above


Correct Option: D
Explanation:

Wetlands provide habitat for a variety of organisms, including fish, birds, and amphibians.

Wetlands are important for maintaining biodiversity because they:

  1. Provide habitat for a variety of organisms

  2. Help control floods and filter water

  3. Store carbon and release oxygen

  4. All of the above


Correct Option: D
Explanation:

Wetlands are important for maintaining biodiversity because they provide habitat for a variety of organisms, help control floods and filter water, and store carbon and release oxygen.

Which of the following is NOT a threat to wetlands?

  1. Pollution

  2. Climate change

  3. Habitat loss

  4. Invasive species


Correct Option: B
Explanation:

Climate change is not a direct threat to wetlands. Pollution, habitat loss, and invasive species are all direct threats to wetlands.

What can be done to protect wetlands?

  1. Reduce pollution

  2. Restore degraded wetlands

  3. Educate the public about the importance of wetlands

  4. All of the above


Correct Option: D
Explanation:

To protect wetlands, we can reduce pollution, restore degraded wetlands, and educate the public about the importance of wetlands.

Wetlands are considered to be one of the most important ecosystems on Earth because they:

  1. Provide habitat for a variety of organisms

  2. Help control floods and filter water

  3. Store carbon and release oxygen

  4. All of the above


Correct Option: D
Explanation:

Wetlands are considered to be one of the most important ecosystems on Earth because they provide habitat for a variety of organisms, help control floods and filter water, and store carbon and release oxygen.

The largest wetland in the world is located in:

The largest wetland in the world is the Pantanal in Brazil.

Wetlands are often referred to as the "kidneys of the Earth" because they:

  1. Filter water and remove pollutants

  2. Provide habitat for a variety of organisms

  3. Store carbon and release oxygen

  4. All of the above


Correct Option: A
Explanation:

Wetlands are often referred to as the "kidneys of the Earth" because they filter water and remove pollutants.

Which of the following is NOT a type of wetland?

  1. Bog

  2. Fen

  3. Swamp

  4. Desert


Correct Option: D
Explanation:

Desert is not a type of wetland. Bogs, fens, and swamps are all types of wetlands.

Wetlands are important for mitigating climate change because they:

  1. Store carbon

  2. Release oxygen

  3. Help control floods

  4. All of the above


Correct Option: D
Explanation:

Wetlands are important for mitigating climate change because they store carbon, release oxygen, and help control floods.

Which of the following is NOT a benefit of wetlands to humans?

  1. Flood control

  2. Water filtration

  3. Food production

  4. Habitat loss


Correct Option: D
Explanation:

Habitat loss is not a benefit of wetlands to humans. Flood control, water filtration, and food production are all benefits of wetlands to humans.

Wetlands are important for maintaining water quality because they:

  1. Filter pollutants

  2. Provide habitat for aquatic plants

  3. Help control floods

  4. All of the above


Correct Option: D
Explanation:

Wetlands are important for maintaining water quality because they filter pollutants, provide habitat for aquatic plants, and help control floods.

Which of the following is NOT a type of wetland plant?

  1. Cattails
