What is the primary cause of coral bleaching?

  1. Increased water temperature

  2. Pollution

  3. Overfishing

  4. Climate change


Correct Option: A
Explanation:

Coral bleaching is primarily caused by elevated water temperatures, which stress corals and cause them to expel the symbiotic algae that provide them with nutrients and color.

Which of the following is an example of a resilience strategy employed by coral reefs?

  1. Rapid growth

  2. Adaptation to changing conditions

  3. Symbiosis with other organisms

  4. All of the above


Correct Option: D
Explanation:

Coral reefs exhibit resilience through various strategies, including rapid growth, adaptation to changing conditions, and symbiotic relationships with other organisms.

How do mangroves contribute to the resilience of coastal ecosystems?

  1. By stabilizing shorelines

  2. By providing habitat for marine life

  3. By filtering pollutants from water

  4. All of the above


Correct Option: D
Explanation:

Mangroves play a crucial role in coastal resilience by stabilizing shorelines, providing habitat for marine life, and filtering pollutants from water.

What is the term used to describe the ability of an ecosystem to recover from disturbances?

  1. Resilience

  2. Adaptation

  3. Sustainability

  4. Biodiversity


Correct Option: A
Explanation:

Resilience refers to the capacity of an ecosystem to absorb disturbances and recover from them, maintaining its structure and function.

Which of the following is an example of a human activity that can negatively impact the resilience of oceanic environments?

  1. Pollution

  2. Overfishing

  3. Climate change

  4. All of the above


Correct Option: D
Explanation:

Human activities such as pollution, overfishing, and climate change can all negatively impact the resilience of oceanic environments.

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

  1. Adaptation

  2. Resilience

  3. Evolution

  4. Acclimation


Correct Option: A
Explanation:

Adaptation refers to the process by which organisms adjust to changes in their environment, often through genetic modifications.

Which of the following is an example of a resilience strategy employed by seagrass meadows?

  1. Rapid growth

  2. Clonal reproduction

  3. Tolerance to environmental stress

  4. All of the above


Correct Option: D
Explanation:

Seagrass meadows exhibit resilience through various strategies, including rapid growth, clonal reproduction, and tolerance to environmental stress.

How do coral reefs contribute to the resilience of coastal ecosystems?

  1. By providing habitat for marine life

  2. By protecting coastlines from erosion

  3. By filtering pollutants from water

  4. All of the above


Correct Option: D
Explanation:

Coral reefs play a crucial role in coastal resilience by providing habitat for marine life, protecting coastlines from erosion, and filtering pollutants from water.

What is the term used to describe the ability of an ecosystem to maintain its structure and function despite disturbances?

  1. Stability

  2. Resilience

  3. Equilibrium

  4. Homeostasis


Correct Option: B
Explanation:

Resilience refers to the capacity of an ecosystem to absorb disturbances and recover from them, maintaining its structure and function.

Which of the following is an example of a human activity that can positively impact the resilience of oceanic environments?

  1. Pollution reduction

  2. Sustainable fishing practices

  3. Climate change mitigation

  4. All of the above


Correct Option: D
Explanation:

Human activities such as pollution reduction, sustainable fishing practices, and climate change mitigation can all positively impact the resilience of oceanic environments.

What is the term used to describe the process by which ecosystems change over time in response to disturbances?

  1. Succession

  2. Resilience

  3. Adaptation

  4. Evolution


Correct Option: A
Explanation:

Succession refers to the process by which ecosystems change over time in response to disturbances, leading to the establishment of new communities.

Which of the following is an example of a resilience strategy employed by salt marshes?

  1. Rapid growth

  2. Tolerance to salinity and flooding

  3. Ability to trap and store sediment

  4. All of the above


Correct Option: D
Explanation:

Salt marshes exhibit resilience through various strategies, including rapid growth, tolerance to salinity and flooding, and the ability to trap and store sediment.

How do mangroves contribute to the resilience of coastal ecosystems against sea-level rise?

  1. By trapping sediment and building up land

  2. By providing habitat for marine life

  3. By filtering pollutants from water

  4. All of the above


Correct Option: D
Explanation:

Mangroves play a crucial role in coastal resilience against sea-level rise by trapping sediment and building up land, providing habitat for marine life, and filtering pollutants from water.

What is the term used to describe the ability of an ecosystem to recover from disturbances and return to its original state?

  1. Resilience

  2. Stability

  3. Equilibrium

  4. Homeostasis


Correct Option: A
Explanation:

Resilience refers to the capacity of an ecosystem to absorb disturbances and recover from them, maintaining its structure and function.

Which of the following is an example of a human activity that can negatively impact the resilience of oceanic environments?

  1. Pollution

  2. Overfishing

  3. Climate change

  4. All of the above


Correct Option: D
Explanation:

Human activities such as pollution, overfishing, and climate change can all negatively impact the resilience of oceanic environments.
