All Flashcards
What is the effect of nutrient runoff on coastal wetlands?
Eutrophication, algal blooms, reduced oxygen levels, and decreased biodiversity.
What is the effect of rising sea levels on coastal wetlands?
Inundation, habitat loss, and saltwater intrusion.
What causes coral bleaching?
Ocean acidification and rising temperatures.
What is the impact of climate change on marine ecosystems?
Coral bleaching, habitat loss, and changes in species distribution.
What is the effect of pollution on aquatic biomes?
Toxin introduction, habitat destruction, and decreased biodiversity.
What is the effect of dredging on coastal wetlands?
Habitat destruction.
What is the effect of development on coastal wetlands?
Habitat loss.
What is the effect of increased nutrient runoff on coastal wetlands?
Increased nutrient runoff leads to eutrophication, algal blooms, and reduced oxygen levels.
What is the effect of rising sea levels on coastal wetlands?
Rising sea levels can lead to inundation, habitat loss, and saltwater intrusion.
What causes coral bleaching?
Ocean acidification and rising temperatures cause coral bleaching.
What is the impact of pollution on aquatic biomes?
Pollution can introduce toxins, reduce water quality, and harm aquatic organisms.
What is the effect of climate change on marine ecosystems?
Climate change leads to ocean acidification, rising temperatures, and coral bleaching, affecting marine life.
What is the impact of dredging on coastal wetlands?
Dredging can destroy habitats and disrupt the ecosystem.
What is the impact of development on coastal wetlands?
Development can cause habitat loss and reduce the ability of wetlands to provide ecosystem services.
Why are aquatic biomes important?
Vital for biodiversity, water cycle, habitats, and human activities like food and recreation.
Why do rivers have high oxygen?
Fast-moving water increases oxygen levels, benefiting aquatic life.
What is the importance of wetlands?
Prevent floods, filter pollutants, and provide habitat for migrating birds.
Why are salt marshes productive?
Rivers bring nutrients, supporting plant growth and coastal protection.
What role do mangrove roots play?
Protect coastline from storms and provide habitat.
Why are coral reefs biodiverse?
Provide complex three-dimensional habitats supporting many species.
Why do corals need sunlight?
They rely on photosynthetic algae for food.
What is the significance of the photic zone?
Sunlight allows photosynthesis, supporting primary production.
Why are intertidal zones challenging?
Organisms must adapt to changing conditions like alternating submersion and exposure.
What are ecosystem services?
Benefits biomes provide, such as water filtration, flood control, and habitat.
What factors influence productivity?
Nutrient availability, sunlight, and temperature.
