Coral Reefs Comprehension Quiz

What is coral reef biodiversity and why is it important?

• Coral reef biodiversity is the variety of colors found in coral reefs, and it is important because it makes the reefs look pretty

• Coral reef biodiversity is the number of tourists that visit coral reefs, and it is important because it brings in revenue for the local economy

• Coral reef biodiversity is the different types of rocks found in coral reefs, and it is important because it provides a stable foundation for the reef ecosystem

• Coral reef biodiversity is the variety of species that live within a coral reef ecosystem, and it is important because it supports the overall health and stability of the reef ecosystem, provides essential resources for human populations, and contributes to the global biodiversity.

What are the major threats to coral reefs and how do they impact the ecosystem?

• Coral reefs are not threatened and have no impact on the ecosystem

• The major threats to coral reefs are excessive growth of coral and increased biodiversity

• The major threats to coral reefs include climate change, ocean acidification, overfishing, pollution, and destructive fishing practices. These threats impact the ecosystem by causing coral bleaching, loss of biodiversity, and disruption of the food chain.

• The major threats to coral reefs include lack of sunlight and too much oxygen in the water

Discuss the effects of climate change on coral reefs and their biodiversity.

• Climate change has no impact on coral reefs

• Climate change can lead to coral bleaching, ocean acidification, and extreme weather events, all of which can negatively impact coral reefs and their biodiversity.

• Coral reefs thrive in extreme weather conditions caused by climate change

• Ocean acidification caused by climate change has a positive effect on coral reefs

Explain the role of marine protected areas in coral reef conservation.

• Marine protected areas have no impact on coral reef conservation

• Marine protected areas contribute to the destruction of coral reefs

• Marine protected areas are only for human recreation and not for conservation

• Marine protected areas provide a safe and undisturbed environment for marine life, allowing the reef to recover from human activities and natural disturbances.

How can coral reef restoration help in reversing the damage caused to these ecosystems?

• By cutting down more coral and destroying the ecosystem further

• By ignoring the damage and letting the ecosystem deteriorate

• By introducing more invasive species and increasing pollution

• By replanting damaged coral, removing invasive species, and reducing pollution.

Discuss the importance of coral gardening in the restoration of coral reefs.

• Coral gardening helps in the restoration of coral reefs by growing and planting new coral fragments.

• Coral gardening only harms the coral reefs further.

• Coral gardening is not important for the restoration of coral reefs.

• Coral gardening helps in the restoration of coral reefs by growing and planting new trees.

Describe the symbiotic relationships between corals and zooxanthellae.

• Predatory relationship where corals consume zooxanthellae for energy

• Parasitic relationship where corals steal nutrients from zooxanthellae

• Commensal relationship where corals benefit from zooxanthellae without providing anything in return

• Mutualistic relationship where zooxanthellae provide energy through photosynthesis and corals provide a protected environment and nutrients.

Explain the mutualistic relationship between coral polyps and the fish species that inhabit the reef.

• The fish species prey on the coral polyps, causing harm to the reef ecosystem.

• Coral polyps and fish compete for resources and often harm each other.

• Mutualistic relationship involves providing shelter, protection, and nutrients between coral polyps and fish species.

• Coral polyps provide no benefit to the fish species that inhabit the reef.
