Study Notes
Seagrass Ecosystem
- Seagrasses support a diverse range of marine life, playing a crucial role in ecological functions.
- Notable species in seagrass habitats include 172 fish species, 46 invertebrates, a single species of dugong, and a sea turtle species.
- Seagrass meadows produce over 10 tons of leaves per half hectare annually.
- They contribute to global fisheries, with 12% of the world’s fish catch originating from seagrass areas.
Coral Reef Ecosystem
- Coral reefs, often called the “rainforests of the sea,” are vital ecosystems known for their biodiversity and complexity.
- Philippine coral reefs are home to over 2,000 fish species, 5,000 mollusk species, and 488 coral species.
- Healthy coral reefs can yield up to 20 tons of fish per square kilometer annually, providing essential protein sources for marine life.
- Coral reefs efficiently capture nutrients and sunlight, supporting a wide range of marine organisms.
Mangrove Ecosystem
- One hectare of mangrove forest can produce up to 3.6 tons of litterfall, enhancing nutrient cycling in coastal ecosystems.
- A healthy hectare of mangroves generates approximately 1.08 tons of fish and fishery products every year.
Sandy Beach Systems
- Beaches play a significant role as nesting sites for turtles and habitats for various invertebrates including polychaete worms and bivalve mollusks.
- Sandy beaches provide vital resources:
- Source of food for detritus feeders and prey for birds and fish.
- Accessibility for human consumption of clams.
- Sand extraction for construction purposes.
Economic and Ecological Benefits
- Coastal ecosystems contribute to tourism, recreation, biodiversity, and education.
- Natural resources from marine environments include medicines, tannins, wood for construction and fuel, honey, and alcohol.
- Shore protection is another crucial function of these ecosystems, helping to mitigate coastal erosion.
