All Flashcards
How do buffer zones help protect coastal wetlands?
Reduce nutrient runoff from agricultural fields.
How do cover crops help protect coastal wetlands?
Reduce nutrient runoff from agricultural fields.
Define aquatic biome.
Biome characterized by the presence of water, either freshwater or saltwater.
What is a freshwater biome?
Aquatic biome with low salinity, including lakes, rivers, and wetlands.
What is a marine biome?
Aquatic biome with high salinity, including oceans, coral reefs, and estuaries.
Define a eutrophic lake.
A lake with high productivity due to abundant nutrients.
Define a mesotrophic lake.
A lake with moderate productivity.
Define an oligotrophic lake.
A lake with low productivity due to low nutrient levels.
Define the littoral zone.
Shallow area near the shore of a lake or pond with high photosynthesis.
Define the limnetic zone.
Open water area of a lake or pond where sunlight can reach.
Define the profundal zone.
Deep area of a lake or pond where sunlight cannot reach.
Define the benthic zone.
The muddy bottom of a lake, ocean, or other body of water.
Define salt marsh.
Coastal wetland with non-woody plants, often found in estuaries.
Define mangrove swamp.
Coastal wetland with salt-tolerant trees with submerged roots.
Define intertidal zone.
Area of coastline between high and low tide marks.
Define coral bleaching.
The expulsion of algae from coral, often due to rising temperatures or ocean acidification.
Define photic zone.
The upper layer of the ocean where sunlight penetrates, allowing photosynthesis.
Define aphotic zone.
The deep layer of the ocean where sunlight does not penetrate.
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.
