What are seagrasses?

  1. Flowering plants that grow in the ocean

  2. A type of seaweed

  3. Marine animals that resemble plants

  4. Coral reefs found in shallow waters


Correct Option: A
Explanation:

Seagrasses are unique flowering plants that have adapted to live in the marine environment.

Where are seagrass meadows typically found?

  1. Deep ocean waters

  2. Tropical rainforests

  3. Shallow coastal areas

  4. Polar regions


Correct Option: C
Explanation:

Seagrass meadows thrive in shallow coastal waters, where they receive sunlight for photosynthesis.

What is the primary role of seagrasses in marine ecosystems?

  1. Providing food for fish

  2. Filtering pollutants from the water

  3. Creating habitats for marine life

  4. All of the above


Correct Option: D
Explanation:

Seagrasses play multiple roles, including providing food and shelter for marine life, filtering pollutants, and oxygenating the water.

Which of the following is a major threat to seagrass meadows?

  1. Climate change and rising sea levels

  2. Pollution from land-based activities

  3. Overfishing and habitat destruction

  4. All of the above


Correct Option: D
Explanation:

Seagrass meadows face various threats, including climate change, pollution, overfishing, and habitat destruction.

How do seagrasses contribute to carbon sequestration?

  1. They absorb carbon dioxide during photosynthesis

  2. They store carbon in their roots and sediments

  3. They release oxygen into the atmosphere

  4. Both A and B


Correct Option: D
Explanation:

Seagrasses not only absorb carbon dioxide during photosynthesis but also store carbon in their extensive root systems and surrounding sediments.

Which marine animals rely heavily on seagrass meadows for food and shelter?

  1. Manatees and dugongs

  2. Sea turtles

  3. Various fish species

  4. All of the above


Correct Option: D
Explanation:

Seagrass meadows provide essential food and shelter for a diverse range of marine animals, including manatees, dugongs, sea turtles, and numerous fish species.

What is the term used to describe the process of seagrass restoration?

  1. Reforestation

  2. Seagrass transplantation

  3. Rewilding

  4. Marine conservation


Correct Option: B
Explanation:

Seagrass transplantation involves transplanting seagrass shoots or seeds from healthy meadows to degraded areas to restore and expand seagrass populations.

Which international agreement specifically addresses the conservation and sustainable use of marine and coastal ecosystems, including seagrasses?

  1. Paris Agreement

  2. Kyoto Protocol

  3. Convention on Biological Diversity

  4. Montreal Protocol


Correct Option: C
Explanation:

The Convention on Biological Diversity (CBD) includes provisions for the conservation and sustainable use of marine and coastal ecosystems, including seagrasses.

What is the main objective of seagrass conservation efforts?

  1. Preserving existing seagrass meadows

  2. Restoring degraded seagrass habitats

  3. Educating the public about seagrass importance

  4. All of the above


Correct Option: D
Explanation:

Seagrass conservation efforts aim to preserve existing meadows, restore degraded habitats, and raise awareness about the significance of seagrasses.

Which human activity is a significant contributor to seagrass decline?

  1. Sustainable fishing practices

  2. Coastal development and dredging

  3. Marine protected area establishment

  4. Seagrass transplantation projects


Correct Option: B
Explanation:

Coastal development and dredging activities can destroy or fragment seagrass meadows, leading to their decline.

What is the primary reason for the decline of seagrass meadows worldwide?

  1. Natural disasters

  2. Climate change and human activities

  3. Overpopulation of marine animals

  4. Competition from other marine plants


Correct Option: B
Explanation:

Climate change, pollution, coastal development, and overfishing are major factors contributing to the decline of seagrass meadows globally.

Which of the following is NOT a benefit of seagrass meadows?

  1. Providing food and shelter for marine life

  2. Filtering pollutants and improving water quality

  3. Contributing to carbon sequestration and climate regulation

  4. Causing erosion and damaging coral reefs


Correct Option: D
Explanation:

Seagrass meadows do not cause erosion or damage coral reefs; instead, they help stabilize sediments and provide a buffer zone between waves and the shoreline.

What is the term used to describe the process of seagrass die-off?

  1. Seagrass decline

  2. Seagrass wasting disease

  3. Seagrass bleaching

  4. Seagrass mortality


Correct Option: D
Explanation:

Seagrass mortality refers to the widespread die-off of seagrass meadows due to various factors such as disease, pollution, or environmental stress.

Which of the following is NOT a conservation strategy for seagrass meadows?

  1. Establishing marine protected areas

  2. Reducing pollution and nutrient runoff

  3. Implementing sustainable fishing practices

  4. Introducing non-native seagrass species


Correct Option: D
Explanation:

Introducing non-native seagrass species can disrupt the natural ecosystem and potentially harm native species.

What is the significance of seagrass meadows in terms of biodiversity?

  1. They support a diverse array of marine life

  2. They provide breeding and nursery grounds for many species

  3. They contribute to the overall health and productivity of marine ecosystems

  4. All of the above


Correct Option: D
Explanation:

Seagrass meadows are hotspots of biodiversity, providing habitat, food, and shelter for a wide range of marine organisms, contributing to the overall health and productivity of marine ecosystems.
