What are the environmental benefits of oyster reefs?

• Improving water quality, enhancing biodiversity, and protecting coastlines from erosion.

• Worsening water pollution, decreasing species diversity, and exacerbating coastal erosion.

• Reducing water pollution, increasing species extinction, and causing coastal erosion.

• Decreasing water quality, reducing biodiversity, and contributing to coastal erosion.

What are some threats to oyster populations?

• overfishing, habitat destruction, pollution, and climate change

• overpopulation, genetic mutations, predation, and commercial harvesting

• tourism, recreational activities, coastal development, and natural disasters

• disease outbreaks, invasive species, ocean acidification, and sedimentation

How do oysters contribute to water quality?

• Oysters increase water pollution.

• Oysters release harmful toxins into the water.

• Oysters have no impact on water quality.

• Oysters filter and purify water.

What is the role of oysters in the ecosystem?

• Oysters are predators that eat other species in the ecosystem.

• Oysters have no role in the ecosystem.

• Oysters contribute to water pollution and harm other species in the ecosystem.
