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

  1. Flood control and water storage

  2. Groundwater recharge

  3. Water purification

  4. All of the above


Correct Option: D
Explanation:

Wetlands play a crucial role in the hydrological cycle by controlling floods, recharging groundwater aquifers, and purifying water through natural filtration processes.

Which of the following is NOT a type of wetland?

  1. Bog

  2. Fen

  3. Marsh

  4. Desert


Correct Option: D
Explanation:

Bogs, fens, and marshes are all types of wetlands, while deserts are characterized by arid conditions and lack of water.

What is the primary source of nutrients for plants in wetlands?

  1. Atmospheric deposition

  2. Surface runoff

  3. Groundwater seepage

  4. Decomposition of organic matter


Correct Option: D
Explanation:

In wetlands, the decomposition of organic matter by microorganisms releases nutrients that are essential for plant growth.

Which of the following is NOT a characteristic of wetland soils?

  1. High organic matter content

  2. Poor drainage

  3. High oxygen content

  4. Anaerobic conditions


Correct Option: C
Explanation:

Wetland soils are typically characterized by high organic matter content, poor drainage, and anaerobic conditions due to the lack of oxygen in the soil.

What is the term used to describe the process by which wetlands remove pollutants from water?

  1. Bioremediation

  2. Phytoremediation

  3. Biofiltration

  4. All of the above


Correct Option: D
Explanation:

Wetlands employ various processes to remove pollutants from water, including bioremediation (microbial degradation), phytoremediation (plant uptake), and biofiltration (filtration through wetland vegetation).

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

  1. Flood control

  2. Water purification

  3. Biodiversity conservation

  4. Agricultural drainage


Correct Option: D
Explanation:

While wetlands provide numerous benefits, agricultural drainage is not a direct benefit to humans, as it involves the conversion of wetlands for agricultural purposes.

What is the primary threat to wetlands worldwide?

  1. Climate change

  2. Pollution

  3. Habitat destruction

  4. All of the above


Correct Option: D
Explanation:

Wetlands face multiple threats, including climate change, pollution, and habitat destruction due to human activities such as urbanization, agriculture, and industrial development.

Which international treaty aims to protect and conserve wetlands of international importance?

  1. Ramsar Convention

  2. Kyoto Protocol

  3. Paris Agreement

  4. Convention on Biological Diversity


Correct Option: A
Explanation:

The Ramsar Convention, also known as the Convention on Wetlands, is an international treaty that provides the framework for the conservation and wise use of wetlands and their resources.

What is the term used to describe the gradual loss of oxygen in wetland soils?

  1. Eutrophication

  2. Acidification

  3. Anaerobiosis

  4. Salinization


Correct Option: C
Explanation:

Anaerobiosis refers to the depletion of oxygen in wetland soils, leading to the creation of conditions where microorganisms can thrive in the absence of oxygen.

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

  1. Cattails

  2. Reeds

  3. Mangroves

  4. Cacti


Correct Option: D
Explanation:

Cattails, reeds, and mangroves are all types of wetland plants, while cacti are adapted to arid environments and are not typically found in wetlands.

What is the term used to describe the process by which wetlands are converted to other land uses?

  1. Reclamation

  2. Restoration

  3. Conservation

  4. Mitigation


Correct Option: A
Explanation:

Reclamation refers to the conversion of wetlands to other land uses, such as agriculture, development, or infrastructure projects.

Which of the following is NOT a wetland ecosystem service?

  1. Flood control

  2. Water purification

  3. Carbon sequestration

  4. Mineral extraction


Correct Option: D
Explanation:

Flood control, water purification, and carbon sequestration are all ecosystem services provided by wetlands, while mineral extraction is not a natural process associated with wetlands.

What is the term used to describe the process of restoring degraded wetlands to their natural state?

  1. Rehabilitation

  2. Mitigation

  3. Conservation

  4. Preservation


Correct Option: A
Explanation:

Rehabilitation refers to the process of restoring degraded wetlands to their natural state through active intervention and management practices.

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

  1. Waterfowl

  2. Amphibians

  3. Reptiles

  4. Kangaroos


Correct Option: D
Explanation:

Waterfowl, amphibians, and reptiles are commonly found in wetlands, while kangaroos are typically associated with grasslands and woodlands.

What is the term used to describe the process by which wetlands are protected and managed for future generations?

  1. Conservation

  2. Preservation

  3. Restoration

  4. Mitigation


Correct Option: A
Explanation:

Conservation refers to the protection and management of wetlands to ensure their long-term viability and ecological integrity.
