Exploring Aquatic Ecosystems: The Importance of Wetlands and Marine Environments
Aquatic ecosystems, including wetlands and marine environments, are vital for biodiversity and environmental health. Wetlands serve as natural filtration systems, protect shorelines from erosion, and are crucial breeding grounds for commercially important species. Marine ecosystems encompass estuaries, salt marshes, mangrove swamps, barrier islands, coral reefs, and the open ocean—each rich in nutrients and diverse life forms. These habitats support countless species and contribute significantly to marine biological productivity, underscoring the need for their conservation and protection.

Presentation Transcript
Wetlands • Wetlands contain fresh water for part of the year -trap and filter sediments and pollutants -protect shorelines from erosion -spawning grounds for many commercially important species -habitat for rare and endangered animals and plants • Includes marshes and swamps • Act as transitional areas between freshwater and saltwater
Marine Ecosystems • Estuary (FW and SW) • Salt marsh • Mangrove swamps • Barrier Islands • Coral reef • Open ocean
Estuary • area where freshwater from a river meets salt water from the ocean -very productive ecosystems -rich in nutrients and minerals -plenty of sunlight (shallow water)
Salt marsh • Develop in areas where estuaries deposit nutrient rich mud • Characterized by marsh grass • Provide support for clams, fish, crabs, shrimp, and aquatic birds • Absorb pollutants and protect • inland areas
Mangrove Swamp • tree vegetation that grows in the muddy coastal areas between high and low water • mangrove forests protect the coastline from erosion; provide nursery grounds for fish, shrimp, clams, crabs and snails • provide food via • nutrient-rich mud • and leaf litter.
Approximately one-third of all marine biological productivity occurs along coastal areas. These areas include mangroves, salt marshes, tidal zones and sea grass beds.
Barrier Island • These geographic features serve as protection for mainland and coastal wetlands
Coral Reef One of the worlds most biologically diverse ecosystems 42% at low risk 31% at medium risk 27% at high risk
Open Ocean • Represents 65% of the Earth oceans. • Some areas of open ocean contain little or no life at all, while other areas support large numbers of species • Approximately 10% of all • marine life is found in the • open ocean. Marlins, Tuna, Dolphins, Swordfish, and Sharks.
