How would you describe underwater grasses?

# data[].attributes.body
There are many different types of underwater grasses so I cannot hold all the species of underwater grasses to one description. Underwater grasses are green and can be darker shades of green. They all have leaves, but the size, shape, width, length, and number of the leaves depend on the species. They all have rhizomes, but the size depends on the species.

Underwater grasses can cover large areas which can be seen from space. Fishermen all around the world look for underwater grass beds for the amount of fish that live in them.

What is the importance of underwater grasses to the Chesapeake Bays's ecosystem?

# data[].attributes.body
Underwater grasses absorb nutrients, slow the flow the water, and their roots trap sediment. This prevents erosion, buffers coastlines against storms and, improves water quality. In nutrient low waters, underwater grasses take nutrients from the ground and release it into the water. Green sea turtles and waterfowl eat underwater grasses. Underwater grasses provide shelter for young and molting blue crabs. Zooplankton eat decaying underwater grasses. Small invertebrates attach themselves to the stem or leaves of underwater grasses. This includes barnacles, sponges, sea slugs and sea squirts. Fish such as spot, croakers, weakfish, Atlantic menhaden, white perch, and American shad have nurseries in underwater grass beds that are safe from predators. Since underwater grasses are producers, if they disappear the organisms that depend on underwater grasses for food, shelter, and nurseries will die out. The organisms that depend on those organisms will die because their food source is gone. This continues until it reaches the top predators. When the top predators die out, the other organisms it eats will increase in population because nothing is hunting them. Then the animals that are eaten by the other organisms that are eaten by the top predators will die out because the other organisms will completely deplete their food source. This eventually reaches the plankton. The organisms that depleted their food source will die out because they don't have anything to eat.

Many organisms depend or use underwater grasses. Young and molting blue crabs hide in underwater grasses to hide from predators while their shell is soft, making them vulnerable. Fish such as spot, croakers, weakfish, Atlantic menhaden, white perch, and American shad have nurseries in underwater grass beds that are safe from predators. These relationships are examples of commensalism. Small invertebrates live on underwater grasses, in return they eat algae that might stunt the growth of underwater grasses and live on them. This an example of mutualism.

What challenges do underwater grasses face?

# data[].attributes.body
Underwater grasses face many challenges that hurt the population. This includes dredging, wind driven waves, storms, rays and skates ripping up sea grass, excess nutrients (eutrophication), boat anchors and propellers stirring up sediment (suffocating underwater grasses), disease, changes in temperature, the removal of fish and invasive seaweed.

With what other organisms do underwater grasses compete or cooperate for resources? 

# data[].attributes.body
The only resources that underwater grasses use are space and sunlight. Algae use sunlight and can make a layer of algae above the surface of the water that can block sunlight from reaching the underwater grasses.

What is the role of underwater grasses in the community?

# data[].attributes.body
Underwater grasses are producers. They are called "lungs of the sea" because one square meter of underwater grasses can produce up to ten liters of oxygen everyday.

# data[].attributes.body
Underwater grasses do not migrate. Their roots keep them from moving around.

# data[].attributes.body
Underwater grasses live in the Chesapeake Bay's streams, creeks, and rivers as well as the Chesapeake Bay itself.
