Study Notes
Importance of Seagrass Meadows
- One of the important roles of seagrass meadows is to provide habitat for various marine life.
Marine Life in Seagrass Meadows
- Seagrass meadows serve as habitats for a diverse range of marine life, including fish, as well as other species such as invertebrates, crustaceans, and mollusks.
Seagrass Meadows and Ocean Acidity
- Seagrass meadows help mitigate the effects of ocean acidity by absorbing carbon dioxide from the atmosphere.
Fishing Productivity
- Seagrass meadows are estimated to support around 25% of global fishing productivity.
Activities Enhanced by Seagrass Meadows
- Apart from fishing, seagrass meadows also enhance activities such as tourism, shoreline protection, and water quality improvement.
Nutrient Recycling
- Seagrass meadows contribute to nutrient recycling in the ecosystem by absorbing and storing nutrients from the water and sediments, which are then released back into the ecosystem through decomposition.
