What is the term for the symbiotic relationship between coral polyps and photosynthetic algae?

  1. Mutualism

  2. Commensalism

  3. Parasitism

  4. Amensalism


Correct Option: A
Explanation:

Coral polyps and photosynthetic algae engage in a mutualistic relationship, benefiting each other.

Which of the following is NOT a major threat to coral reefs?

  1. Climate Change

  2. Overfishing

  3. Pollution

  4. Deforestation


Correct Option: D
Explanation:

Deforestation is not a direct threat to coral reefs, although it can indirectly impact them through increased sedimentation and nutrient runoff.

What is the primary function of mangrove forests in relation to coral reefs?

  1. Nutrient Filtration

  2. Wave Attenuation

  3. Habitat Provision

  4. Carbon Sequestration


Correct Option: B
Explanation:

Mangrove forests help protect coral reefs by attenuating wave energy and reducing erosion.

Which island nation is known for its vibrant coral reefs and rich marine biodiversity?

  1. Maldives

  2. Indonesia

  3. Philippines

  4. Madagascar


Correct Option: A
Explanation:

The Maldives is renowned for its stunning coral reefs and diverse marine life.

What is the process by which coral reefs can recover from bleaching events?

  1. Resilience

  2. Adaptation

  3. Regeneration

  4. Acclimatization


Correct Option: C
Explanation:

Coral reefs can regenerate and recover from bleaching events through the growth of new coral colonies.

Which type of island is formed by the accumulation of sediment and organic matter over time?

  1. Continental Island

  2. Volcanic Island

  3. Barrier Island

  4. Artificial Island


Correct Option: C
Explanation:

Barrier islands are formed by the accumulation of sediment and organic matter.

What is the term for the process by which coral reefs grow vertically in response to rising sea levels?

  1. Uplift

  2. Accretion

  3. Submergence

  4. Erosion


Correct Option: B
Explanation:

Which type of island is formed by the deposition of sediment by rivers and streams?

  1. Continental Island

  2. Volcanic Island

  3. Barrier Island

  4. Delta Island


Correct Option: D
Explanation:

Delta islands are formed by the deposition of sediment by rivers and streams.

What is the term for the process by which coral reefs can adapt to changing environmental conditions?

  1. Resilience

  2. Adaptation

  3. Regeneration

  4. Acclimatization


Correct Option: B
Explanation:

Coral reefs can adapt to changing environmental conditions through various mechanisms, such as genetic adaptation and phenotypic plasticity.
