What is the primary function of salt marshes in coastal ecosystems?

  1. Providing habitat for marine mammals

  2. Filtering pollutants from water

  3. Generating oxygen through photosynthesis

  4. Absorbing carbon dioxide from the atmosphere


Correct Option: B
Explanation:

Salt marshes act as natural filters, removing pollutants and excess nutrients from water before it reaches the ocean.

Which of the following is a characteristic feature of salt marshes?

  1. Sandy beaches

  2. Coral reefs

  3. Mangrove forests

  4. Tidal mudflats


Correct Option: D
Explanation:

Tidal mudflats, formed by the deposition of fine sediments, are a defining feature of salt marshes.

What is the ecological significance of salt marshes for marine life?

  1. Spawning grounds for fish

  2. Nursery habitat for juvenile fish and shellfish

  3. Feeding grounds for migratory birds

  4. All of the above


Correct Option: D
Explanation:

Salt marshes provide critical habitats for various marine species, including spawning grounds, nursery areas, and feeding grounds.

Which human activity poses the most significant threat to salt marshes?

  1. Climate change

  2. Pollution

  3. Overfishing

  4. Habitat destruction


Correct Option: D
Explanation:

Habitat destruction, primarily due to coastal development and land reclamation, is the leading threat to salt marshes.

What is the primary goal of salt marsh conservation efforts?

  1. Preserving biodiversity

  2. Mitigating climate change

  3. Promoting sustainable fishing practices

  4. Reducing pollution


Correct Option: A
Explanation:

Salt marsh conservation aims to protect the unique biodiversity and ecological functions of these coastal wetlands.

Which international agreement specifically addresses the conservation of salt marshes?

  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 focuses on the conservation and wise use of wetlands, including salt marshes.

How does climate change impact salt marshes?

  1. Rising sea levels

  2. Increased frequency of storms

  3. Changes in precipitation patterns

  4. All of the above


Correct Option: D
Explanation:

Climate change affects salt marshes through rising sea levels, increased storm frequency and intensity, and changes in precipitation patterns.

What is the role of salt marshes in carbon sequestration?

  1. They absorb carbon dioxide from the atmosphere

  2. They release carbon dioxide into the atmosphere

  3. They have no impact on carbon dioxide levels

  4. They increase carbon dioxide levels in the atmosphere


Correct Option: A
Explanation:

Salt marshes are efficient carbon sinks, capturing and storing carbon dioxide from the atmosphere.

Which conservation strategy involves restoring degraded salt marshes to their natural state?

  1. Habitat restoration

  2. Habitat creation

  3. Habitat protection

  4. Habitat enhancement


Correct Option: A
Explanation:

Habitat restoration aims to restore degraded salt marshes to their original condition, improving their ecological functions and biodiversity.

How can local communities contribute to salt marsh conservation?

  1. Reducing pollution

  2. Participating in volunteer restoration projects

  3. Educating others about the importance of salt marshes

  4. All of the above


Correct Option: D
Explanation:

Local communities can support salt marsh conservation through pollution reduction, volunteering in restoration projects, and raising awareness about the importance of these ecosystems.

What is the term used to describe the gradual landward movement of salt marshes in response to rising sea levels?

  1. Salt marsh migration

  2. Salt marsh retreat

  3. Salt marsh expansion

  4. Salt marsh inundation


Correct Option: A
Explanation:

Salt marsh migration refers to the process by which salt marshes move inland in response to rising sea levels, maintaining their elevation relative to the water.

Which type of vegetation is commonly found in salt marshes?

  1. Mangroves

  2. Seagrasses

  3. Salt-tolerant grasses

  4. Coral reefs


Correct Option: C
Explanation:

Salt marshes are characterized by the presence of salt-tolerant grasses and other halophytic plants that can withstand high salinity levels.

What is the primary source of nutrients for salt marshes?

  1. Fertilizers from agricultural runoff

  2. Atmospheric deposition

  3. Tidal exchange

  4. Groundwater discharge


Correct Option: C
Explanation:

Salt marshes receive nutrients primarily through tidal exchange, which brings in nutrients from the ocean.

Which animal species is known for its role in creating and maintaining salt marsh habitats?

  1. Oysters

  2. Crabs

  3. Mussels

  4. Shrimp


Correct Option: A
Explanation:

Oysters play a crucial role in salt marsh ecosystems by filtering water, creating habitats for other species, and stabilizing sediments.

What is the term used to describe the process by which salt marshes trap and store carbon dioxide?

  1. Carbon sequestration

  2. Carbon fixation

  3. Carbon cycling

  4. Carbon release


Correct Option: A
Explanation:

Carbon sequestration refers to the process by which salt marshes capture and store carbon dioxide from the atmosphere, contributing to climate change mitigation.
