Which of the following is NOT a benefit of wetlands in climate change mitigation?

  1. Carbon sequestration

  2. Flood control

  3. Water purification

  4. Emission of greenhouse gases


Correct Option: D
Explanation:

Wetlands are known for their ability to absorb and store carbon dioxide, thus helping to mitigate climate change. They do not emit greenhouse gases.

Mangroves are particularly effective in carbon sequestration due to their:

  1. High rate of photosynthesis

  2. Extensive root systems

  3. Ability to store carbon in their biomass

  4. All of the above


Correct Option: D
Explanation:

Mangroves excel in carbon sequestration due to their rapid growth, extensive root systems that trap sediment and organic matter, and their ability to store carbon in their biomass.

Wetlands and mangroves contribute to climate change adaptation by:

  1. Reducing the impacts of floods and storms

  2. Providing habitats for wildlife

  3. Improving water quality

  4. All of the above


Correct Option: D
Explanation:

Wetlands and mangroves play a crucial role in climate change adaptation by reducing the impacts of floods and storms, providing habitats for wildlife, and improving water quality.

Which of the following is NOT a threat to wetlands and mangroves?

  1. Deforestation

  2. Pollution

  3. Climate change

  4. Conservation efforts


Correct Option: D
Explanation:

Deforestation, pollution, and climate change are major threats to wetlands and mangroves. Conservation efforts, on the other hand, aim to protect and restore these ecosystems.

The Ramsar Convention is an international treaty that aims to:

  1. Protect wetlands and their resources

  2. Promote sustainable use of wetlands

  3. Encourage international cooperation on wetland conservation

  4. All of the above


Correct Option: D
Explanation:

The Ramsar Convention is a global agreement that seeks to protect wetlands and their resources, promote their sustainable use, and encourage international cooperation on wetland conservation.

Which country has the largest area of mangroves in the world?

  1. Indonesia

  2. Brazil

  3. India

  4. Australia


Correct Option: A
Explanation:

Indonesia is home to the largest mangrove forests in the world, covering an area of approximately 3.3 million hectares.

The Sundarbans, a UNESCO World Heritage Site, is located in which country?

  1. India and Bangladesh

  2. Myanmar and Thailand

  3. Vietnam and Cambodia

  4. Philippines and Indonesia


Correct Option: A
Explanation:

The Sundarbans, the largest mangrove forest in the world, is shared between India and Bangladesh.

What is the primary function of mangroves in coastal ecosystems?

  1. Providing habitat for marine life

  2. Protecting coastlines from erosion

  3. Filtering pollutants from water

  4. All of the above


Correct Option: D
Explanation:

Mangroves provide habitat for marine life, protect coastlines from erosion, and filter pollutants from water, making them vital components of coastal ecosystems.

Which of the following is NOT a consequence of mangrove deforestation?

  1. Increased coastal erosion

  2. Loss of biodiversity

  3. Reduced carbon sequestration

  4. Improved water quality


Correct Option: D
Explanation:

Mangrove deforestation leads to increased coastal erosion, loss of biodiversity, and reduced carbon sequestration. It does not improve water quality.

What is the term used to describe the process by which wetlands absorb and store carbon dioxide?

  1. Carbon sequestration

  2. Carbon storage

  3. Carbon capture

  4. Carbon fixation


Correct Option: A
Explanation:

Carbon sequestration is the process by which wetlands absorb and store carbon dioxide from the atmosphere.

Which of the following is NOT a strategy for conserving and restoring wetlands and mangroves?

  1. Protecting existing wetlands and mangroves

  2. Restoring degraded wetlands and mangroves

  3. Promoting sustainable use of wetlands and mangroves

  4. Converting wetlands and mangroves to other uses


Correct Option: D
Explanation:

Conserving and restoring wetlands and mangroves involves protecting existing ecosystems, restoring degraded ones, and promoting sustainable use. Converting wetlands and mangroves to other uses is counterproductive to conservation efforts.

Which international agreement specifically addresses the conservation and sustainable use of wetlands?

  1. Ramsar Convention

  2. Kyoto Protocol

  3. Paris Agreement

  4. Convention on Biological Diversity


Correct Option: A
Explanation:

The Ramsar Convention is an international treaty that focuses on the conservation and sustainable use of wetlands.

What is the primary reason why mangroves are effective in reducing coastal erosion?

  1. Their extensive root systems stabilize the soil

  2. Their leaves trap sediment and create new land

  3. They act as natural breakwaters, dissipating wave energy

  4. All of the above


Correct Option: D
Explanation:

Mangroves are effective in reducing coastal erosion due to their extensive root systems, which stabilize the soil, their leaves that trap sediment and create new land, and their ability to act as natural breakwaters, dissipating wave energy.

Which of the following is NOT a benefit of wetlands in terms of water quality?

  1. Filtering pollutants and sediments

  2. Recharging groundwater supplies

  3. Providing habitat for aquatic plants and animals

  4. Releasing harmful toxins into the environment


Correct Option: D
Explanation:

Wetlands provide numerous benefits to water quality, including filtering pollutants and sediments, recharging groundwater supplies, and providing habitat for aquatic plants and animals. They do not release harmful toxins into the environment.

Which of the following is NOT a challenge in conserving and restoring wetlands and mangroves?

  1. Habitat fragmentation

  2. Climate change impacts

  3. Pollution

  4. Public support for conservation efforts


Correct Option: D
Explanation:

Habitat fragmentation, climate change impacts, and pollution are major challenges in conserving and restoring wetlands and mangroves. Public support for conservation efforts is generally positive and not considered a challenge.
