FAQ: 3. How Did The Seagrass Beds In Indonesia Compared To Offshore Waters?

How does seagrass survive in the ocean?

Seagrasses have evolved adaptations to survive in marine environments including salt tolerance and resistance to the energy of waves (rhizomes and roots firmly anchor seagrasses to the sediments and flexible blades offer little resistance to water movement.

How do seagrass meadows in Indonesia help the environment?

Seagrass meadows are a key part of Indonesia’s marine environment providing significant ecosystem service provision such as fisheries support. Seagrasses support fisheries productivity by providing nursery and foraging grounds for commercially important fish and invertebrate species (Unsworth et al., 2014).

Why seagrass is so important to the ocean?

Seagrass is one of the most important ecosystems on this planet, vital to the overall health of the ocean. It provides food and shelter for many different underwater creatures. It helps in coastal protection and it’s a big player in the fight against climate change.

How does seagrass benefit the ocean and marine life?

Seagrasses perform numerous functions: Stabilizing the sea bottom. Providing food and habitat for other marine organisms. Maintaining water quality.

What animals live in seagrass beds?

As a result, seagrasses can be home to many types of fish, sharks, turtles, marine mammals (dugongs and manatees), mollusks (octopus, squid, cuttlefish, snails, bivalves), sponges, crustaceans (shrimp, crabs, copepods, isopods and amphipods) polychaete worms, sea urchins and sea anemones—and the list goes on.

What are the 2 major threats to seagrass beds?

Of the threats assessed, industrial and agricultural run-off, coastal infrastructure development, and dredging were determined to have the greatests impacts on seagrasses globally. These anthropogenic activities disturb seagrasses by increasing water turbidity and physically damaging seagrass habitat.

Why do we have to protect the seagrass beds?

They stabilize and hold bottom sediment even under the force of hurricanes and storms. They provide shelter and refuge for adult and young marine animals, many of which are commercially important. They provide food for fish, sea turtles and other marine animals, including the endangered Dugong and the Green sea turtle.

What is the importance of seagrass beds?

Seagrass stabilizes sediments and prevents erosion along Florida’s coastline. Seagrasses stabilize bottom sediments with their dense roots and rhizomes that form a secure mat. This sediment stabilization and erosion prevention is especially important during storms and hurricanes that often threaten Florida’s coastline.

Why does seagrass die?

The likely primary cause of seagrass loss is reduction in water clarity, both from increased nutrient loading and increased turbidity. Worldwide, anthropogenic nutrient over- enrichment of coastal waters is the factor responsible for much of the reported seagrass decline.

What is the largest habitat on Earth?

The deep-sea is the largest habitat on earth. The area reaches over 4 000m in depth and covers 53% of the sea’s surface, which in turn covers 71% of the world’s surface!

Why are there sea grass beds on the sea?

With root like stems, which extend horizontally under the sea bottom, seagrasses act to stabilize the sediment. These sediments, that would otherwise settle on coral and prevent contact with sunlight, tend to accumulate and become trapped in the seagrass.

What does phytoplankton do for the ocean?

Phytoplankton provide organic matter for the organisms that comprise the vast majority of marine life. They do this by consuming carbon dioxide that would otherwise dissolve in the sea water and make it more acidic. The organisms provide organic matter for the vast majority of the marine food chain.
