What is the term used to describe the variety of life found in marine ecosystems?

  1. Marine biodiversity

  2. Oceanic diversity

  3. Aquatic life

  4. Sea life


Correct Option: A
Explanation:

Marine biodiversity encompasses the wide range of species, habitats, and ecological processes found in marine environments.

Which of the following is NOT a major type of marine ecosystem?

  1. Coral reefs

  2. Mangroves

  3. Deep sea

  4. Tundra


Correct Option: D
Explanation:

Tundra is a terrestrial ecosystem found in cold, treeless regions, while coral reefs, mangroves, and the deep sea are all marine ecosystems.

What is the primary role of coral reefs in marine ecosystems?

  1. Providing habitat for marine life

  2. Filtering pollutants from the water

  3. Producing oxygen through photosynthesis

  4. Regulating ocean currents


Correct Option: A
Explanation:

Coral reefs provide a diverse and complex habitat for a wide variety of marine organisms, including fish, invertebrates, and algae.

How do mangroves contribute to the resilience of coastal ecosystems?

  1. By stabilizing shorelines

  2. By filtering pollutants from the water

  3. By providing habitat for marine life

  4. By absorbing carbon dioxide


Correct Option:
Explanation:

Mangroves play multiple roles in coastal ecosystems, including stabilizing shorelines, filtering pollutants, providing habitat for marine life, and absorbing carbon dioxide.

What is the term used to describe the process by which marine organisms adapt to changing environmental conditions?

  1. Resilience

  2. Adaptation

  3. Acclimatization

  4. Evolution


Correct Option: B
Explanation:

Adaptation refers to the process by which marine organisms adjust their physiological, behavioral, or genetic traits to better suit their changing environment.

Which of the following is NOT a threat to marine biodiversity?

  1. Overfishing

  2. Climate change

  3. Pollution

  4. Deforestation


Correct Option: D
Explanation:

Deforestation is a threat to terrestrial ecosystems, while overfishing, climate change, and pollution are all major threats to marine biodiversity.

How does climate change impact marine biodiversity?

  1. By causing ocean acidification

  2. By raising sea levels

  3. By increasing water temperatures

  4. All of the above


Correct Option: D
Explanation:

Climate change impacts marine biodiversity through multiple mechanisms, including ocean acidification, rising sea levels, and increasing water temperatures.

What is the term used to describe the process by which marine ecosystems recover from disturbances?

  1. Resilience

  2. Restoration

  3. Rehabilitation

  4. Renewal


Correct Option: A
Explanation:

Resilience refers to the ability of marine ecosystems to withstand and recover from disturbances, such as natural disasters or human activities.

Which of the following is an example of a marine protected area?

  1. Great Barrier Reef Marine Park

  2. Yellowstone National Park

  3. Amazon Rainforest

  4. Serengeti National Park


Correct Option: A
Explanation:

The Great Barrier Reef Marine Park is a large marine protected area located in Australia, while Yellowstone National Park, Amazon Rainforest, and Serengeti National Park are terrestrial protected areas.

How can marine biodiversity be conserved and protected?

  1. By reducing overfishing

  2. By mitigating climate change

  3. By reducing pollution

  4. All of the above


Correct Option: D
Explanation:

Conserving and protecting marine biodiversity requires a comprehensive approach that includes reducing overfishing, mitigating climate change, reducing pollution, and implementing effective marine protected areas.

What is the term used to describe the interconnectedness and interdependence of species within a marine ecosystem?

  1. Biodiversity

  2. Ecosystem services

  3. Food web

  4. Ecological balance


Correct Option: C
Explanation:

A food web represents the interconnectedness and interdependence of species within an ecosystem, showing how energy and nutrients flow through different organisms.

Which of the following is NOT a keystone species in marine ecosystems?

  1. Sea otters

  2. Coral

  3. Sharks

  4. Jellyfish


Correct Option: D
Explanation:

Sea otters, coral, and sharks are all keystone species in marine ecosystems, while jellyfish are not typically considered keystone species.

How does marine biodiversity contribute to human well-being?

  1. By providing food and other resources

  2. By regulating climate and weather patterns

  3. By supporting tourism and recreation

  4. All of the above


Correct Option: D
Explanation:

Marine biodiversity contributes to human well-being in multiple ways, including providing food and other resources, regulating climate and weather patterns, and supporting tourism and recreation.

What is the term used to describe the process by which marine organisms migrate from one location to another?

  1. Migration

  2. Dispersal

  3. Recruitment

  4. Settlement


Correct Option: A
Explanation:

Migration refers to the movement of marine organisms from one location to another, often over long distances, in response to environmental cues or life cycle stages.

How can marine biodiversity be used to develop new medicines and therapies?

  1. By studying the chemical compounds produced by marine organisms

  2. By identifying new genetic resources

  3. By developing new technologies inspired by marine organisms

  4. All of the above


Correct Option: D
Explanation:

Marine biodiversity can be used to develop new medicines and therapies through various approaches, including studying the chemical compounds produced by marine organisms, identifying new genetic resources, and developing new technologies inspired by marine organisms.
