Without Manatee's to eat large quantities of sea grass, the vegetation would become obstructive to Florida Waterways. By limiting vegetation growth they control mosquitos population and overgrowth. Manatee's do not harm any other organisms and have no immediate predators.
Full Answer
Why are manatees important to the ecosystem?
Being purely aquatic herbivorous mammals, Florida manatees have a very special place in the ecosystem, playing a crucial role in the nutrients cycle and in clearing waterways by feeding on aquatic plants.
How are manatees being threatened by coastal development?
Coastal development is threatening manatee habitat in shallow waters where manatees sleep and feed. Manatees depend on sea-grasses and other near-shore ecosystems for food and shelter. These areas are also the most immediately impacted by nutrient run-off from agriculture, which pollutes coastal ecosystems and threatens manatee habitat.
Why are manatees in shallow water?
Some of this algae is toxic and can kill manatees if they eat it. Because manatees feed on sea grass, and sea grass needs sunlight and shallow water to grow, manatees spend most of their time in shallow water.
How do boaters know when a manatee is nearby?
Educational campaigns teach boaters to look for patterns caused by a manatee’s tail on the surface of the water so they'll know if a manatee is nearby and to proceed cautiously through shallow waterways.
How can the protection of just one species such as the manatee benefit other species in the same habitat?
How can the protection of just one species, such as a manatee, benefit other species in the same habitat? With protection of that species, the whole habitat is being protected so the other species inside that habitat are protected as well.
Why might an introduced animal species overrun native species in an ecosystem?
Why might an introduced animal species overrun native species in an ecosystem? Its population size is smaller than those of native species. It is more energy efficient, so it eats less food. It is a predator of the native species.

Can invasive species be beneficial?
The birds that eat the fruit of invasive plants benefit from having an abundant food source in the fall and winter, which increases their survival. Invasive plants can also serve as a source of pollen and nectar for a variety of insect species.
How can invasive species affect an ecosystem?
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
Which of the following pollutants are difficult to remove a DDT B plastic waste C nuclear waste D all of these?
For example, substances such as dichlorodiphenyltrichloroethane (DDT), plastic materials, heavy metals, many chemicals, and nuclear wastes etc., once released into the environment are difficult to remove. These pollutants cannot be degraded by natural processes and are harmful to living organisms.
How do toxic substances travel through the environment describe and contrast the processes of bioaccumulation and biomagnification?
Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms, while biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.
Why do many health organizations call for local exceptions to the ban on DDT?
Why do many health organizations call for local exceptions to the ban on DDT? a) DDT was blamed for problems it never actually caused. Which of the following chemical pollutants can cause harmful algal blooms? Biomagnification of toxic substances means that __________.

WWF’s work in the region protects ecosystems and critical habitat for manatees. This includes efforts to strengthen management plans of marine protected areas and efforts to improve the enforcement of public policy instruments to conserve key areas where manatees live and reproduce.
What do manatees depend on?
Manatees depend on sea-grasses and other near-shore ecosystems for food and shelter. These areas are also the most immediately impacted by nutrient run-off from agriculture, which pollutes coastal ecosystems and threatens manatee habitat.
How long do manatees sleep underwater?
They will often sleep underwater for half a day , coming to the surface for air for 20-minute intervals, and grazing for food in shallow waters.
How deep do manatees live?
BOAT COLLISIONS. Manatees feed and reside in shallow coastal areas – sometimes only 3-6 feet (1-2 meters) underwater. They are curious creatures, and can often be spotted in high-tourism areas as they venture near boats to investigate.
How often do manatees breed?
Manatees have a long reproductive cycle, generally breeding just once every two years, giving birth to a single calf. Manatees help ensure vegetative balance in ecosystems, and their health serves as an indicator to overall marine and ecological well-being.

Also, WWF is working to seek legal protection using the protected area frameworks to safeguard known habitats for manatees. WWF supports the efforts of local organizations to generate information about manatees and to raise awareness and raise awareness about what is needed to protect them.
Why are coastal ecosystems important?
Because coastal ecosystems are such potent "carbon sinks," the loss of these habitats is an important driver of climate change. Intact, these coastal habitats are actually one of our best ways to protect coastal communities from climate change. During hurricanes and other storms, high winds can push walls of water toward shore.
How do hurricanes affect coastal habitats?
During hurricanes and other storms, high winds can push walls of water toward shore. Coastal habitats absorb energy from incoming waves and slow down these storm surges. As sea levels rise and hurricanes become stronger, we will need this protection more than ever.
What are the threats to coastal wetlands?
Habitats under threat. While coastal wetlands are a key defense against climate change, these ecosystems are themselves vulnerable to climate change. In theory, coastal wetlands, whose plants can only survive in specific amounts of saltwater, could adapt to rising sea levels by moving inland.
How do coastal ecosystems store carbon?
Coastal ecosystems are especially good at storing carbon because of the thick, rich layers of soil they build up. In most forests, when trees die, they release their carbon back into the atmosphere. But in many coastal ecosystems, when plants die, they don’t fully break down, and their carbon can stay trapped in water-logged soils for thousands of years. In fact, mangroves store three to five times as much carbon per acre as other tropical forests. 1 Coastal wetlands can also store carbon that comes from other ecosystems, by filtering out carbon-rich sediments suspended in river water as it flows out to sea. Because coastal ecosystems are such potent "carbon sinks," the loss of these habitats is an important driver of climate change.
Why do the Netherlands have salt marshes?
The low-lying Netherlands has started shoring up some of the salt marshes in front of its dykes, to protect this infrastructure, and its citizens, from sea level rise. Some environmental policymakers have also proposed paying coastal landowners for the carbon stored in these ecosystems to prevent their destruction.
Why is there a growing movement to preserve these habitats?
There is a growing movement to preserve these habitats because of all the benefits they provide us. Conservation groups and others are protecting undeveloped land behind coastal ecosystems to help them adapt to sea level rise. The low-lying Netherlands has started shoring up some of the salt marshes in front of its dykes, to protect this infrastructure, and its citizens, from sea level rise. Some environmental policymakers have also proposed paying coastal landowners for the carbon stored in these ecosystems to prevent their destruction.
What are coastal ecosystems?
Coastal ecosystems are the unique habitats formed by plants and other organisms that can thrive at the borders between ocean and land, where they must live in saltwater and changing tides.
What are the threats to manatees?
There are two major threats: loss of habitat and collisions with boats and ship s. As new developments are built along waterways, natural nesting areas are destroyed. Sewage, manure, and fertilizer run-off enters the water and causes algal blooms. Some of this algae is toxic and can kill manatees if they eat it .
How big are manatees?
Did you know that manatees are related to elephants? Manatees are large aquatic mammals, and sometimes they're referred to as “sea cows.” They're very large averaging 10 feet long and 1,200 pounds! But don't let their size fool you: manatees are actually incredibly graceful creatures. They also play an important role in maintaining a healthy ecosystem.
How many species of manatees are there in the world?
While manatees don't have any true natural predators, they have still become endangered. There are three manatee species worldwide – West Indian, West African, and Amazonian. All three are listed as vulnerable to extinction.
Do manatees eat sea grass?
But don't let their size fool you: manatees are actually incredibly graceful creatures. They also play an important role in maintaining a healthy ecosystem. Manatees eat a LOT of sea grass. By doing so, they keep the grass short, which helps maintain the health of the sea grass beds.
Can manatees eat algae?
Some of this algae is toxic and can kill manatees if they eat it. Because manatees feed on sea grass, and sea grass needs sunlight and shallow water to grow, manatees spend most of their time in shallow water. This often leaves them with little room to dive away from oncoming boats, which can lead to deadly collisions.
