Transcript of Seagrass Beds
BY: Luis Moreno
Biotic & Abiotic Factors
Biotic factors include coral, seaweed, algae, fish, plankton , sea turtles, manatees, shrimp, and crabs.
Abiotic factors include rocks, sand, water, salt, sunlight, temperature,and carbon.
Where can they be found?
Seagrasses provide an important habitat to a number of organisms. Some use seagrass beds as nursery areas, others use it as shelter there their whole lives. Larger animals like manatees and sea turtles feed on animals that live in the seagrass beds.
Seagrass are a type of aquatic vegetation that has evolved from terrestrial plants and have become specialized to live in marine environments. They are angiosperms.Like terrestrial plants, seagrasses have leaves, roots, conducting tissues, flowers and seeds, and make their own food through photosynthesis.
What are seagrasses?
They function as wave and current break , seagrass prevents sediment stabilizers and offer protection against shoreline and coastal erosion.
Human activities like runoff from land into the ocean impact this ecosystem. Also Nutrients, such as those from fertilizers and pollution, wash into the water and can cause algal blooms, which block the necessary sunlight from reaching the seafloor.
Seagrass beds can be found on ocean coast or river estuaries, bays, lagoons, and and in both temperate and tropical regions.
They’re known as the “lungs of the sea” because one square meter of seagrass can generate 10 liters of oxygen every day
It’s estimated that 29% of the world’s seagrass meadows have died off in the past century, with 1.5% more disappearing each year
Vast seagrass beds also capture and store a huge amount of carbon from the atmosphere even more than the world's forests per hectare. It’s estimated that the world’s seagrass meadows capture 27.4 million tons of carbon each year!
