Question

1. true or false. coastal ecosystems include beaches, estuaries, mangrove forests, coral reefs, salt marshes and seagrass beds.
2. true or false. estuaries are completely isolated from the ocean and do not support marine species.
3. true or false. mangrove forests help stabilize shorelines and reduce erosion through their complex root systems.
4. true or false. salt marshes are freshwater wetlands that do not experience tidal flooding.
5. true or false. seagrass beds provide important habitat for fish, sea turtles, and marine mammals.
6. true or false. human activities have had a positive impact on the health of coastal ecosystems, increasing biodiversity.
7. true or false. the chesapeake bay is the largest estuary in the united states and supports a wide range of species.
8. true or false. nutrient pollution from agricultural runoff has improved water quality in the chesapeake bay.
9. true or false. marine protected areas (mpas) restrict human activities to help conserve coastal ecosystems.
10. true or false. climate change has no impact on coastal ecosystems, keeping them stable and healthy.

Explanation:

1. Coastal ecosystems indeed include beaches, estuaries, mangrove forests, coral reefs, salt marshes and seagrass beds.
2. Estuaries are semi - enclosed bodies of water where freshwater meets saltwater and support many marine species.
3. Mangrove forests have complex root systems that help stabilize shorelines and reduce erosion.
4. Salt marshes are coastal wetlands that experience tidal flooding and are not freshwater wetlands.
5. Seagrass beds are important habitats for many marine organisms like fish, sea turtles and marine mammals.
6. Human activities generally have a negative impact on coastal ecosystems, reducing biodiversity.
7. The Chesapeake Bay is the largest estuary in the US and supports a wide variety of species.
8. Nutrient pollution from agricultural runoff degrades water quality in estuaries like the Chesapeake Bay.
9. Marine Protected Areas (MPAs) restrict human activities to conserve coastal ecosystems.
10. Climate change has significant negative impacts on coastal ecosystems, such as sea - level rise and ocean acidification.
