The Everglades: Freshwater Biome
Transcript of The Everglades: Freshwater Biome
is a freshwater biome. It is located at 26.0°N 80.7°W
and is 733.6 sq miles. Phytoplankton
Freshwater Biomes Alligator Snapping Turtles are usually found in the deeper waters of the everglades, mainly swamps. They can be predators or scavengers. While they can help by cleaning up decaying matter, they can also impact fish population due to the large amount of food they consume. Example food web for animals commonly found in the everglades. The Everglades To be a freshwater biome, there must be a body of water with less than 1% salt concentration. The everglades has a mild climate and considered a wetland, with "a mosaic of freshwater ponds winding throughout" Abiotic Factors Lots of sunshine
Carbon Dioxide These conditions are important to the everglades because they help support its diverse life. For example, carbon dioxide is key for the producers here. The everglades diversity of life makes it special. Over 350 species
it the most
significant breeding grounds for subtropical wading birds. This turtle obtains its energy from its food. The Alligator Snapping Turtle is a carnivore. It eats a variety of things such as: fish, minnows, dead fish, snakes, snails, crayfish, and even other turtles! As the snapping turtle eats, around 10% the energy from its meal is passed on to it. Because of this, the turtle eats large amounts of food every day. producers tertiary consumers primary consumers secondary consumers Decomposers like worms fungi and bacteria break down dead organisms and recycle the energy back into the soil for producers Biomass is the amount of organic matter making up an organism in a habitat. For aquatic ecosystems in particular more biomass can be supported at higher tropic levels Alligators Birds Fish Snails Algae Competition Mutualism Commensalism Symbiosis The vast amounts of birds in the everglades all compete for places to make nests and breed Hydras and algae are an example. Algae gets nutrients (nitrogen) and the hydra receives products of photosynthesis resulting in better growth. Parasitism Leeches and nematodes are examples of parasites. They steal nutrients from their hosts. An example of this is the oyster and red mangrove. The oyster gets protection from the mangroves branches, but the mangrove gets nothing in The amount of energy limits the life in the ecosystem because the food chain and trophic levels depend on it. If there was a lack of sunlight, the key source of all energy, phytoplankton would not maintain the constant rate of photosynthesis they do now, some would die and others would have limited amounts of energy in them. Then when the zooplankton came along to eat them, and since they only absorb 10% of those nutrients, would have a greater lack of energy, then the minnows eat those, and the bass those, and the blue heron those, and the alligator those. Each step is losing more and more energy. If there was an insufficient amount of energy in the start, there will be little to none when it travels all the way to get to the alligator. If decomposers didn’t recycle energy of the dead animals, the energy would go to waste and not be recycled back into the ecosystem. Worms bacteria and fungi can recycle energy back into the soil of the wetlands, where plants use its nutrients, then get eaten by herbivores. The cycle continues on and on. All of the food chain affected by the amount of available matter and energy.

Human Interference "Human impact on the Everglades is substantial. Rapid population growth in southern Florida requires massive supplies of fresh water, and agriculture consumes more water. Water for human uses is derived from pumping ground water and diversion of surface water via numerous canals. The net consequence is diminished flow of surface water through the Everglades drainage system. Surface water in the Everglades is naturally nutrient poor. However, upstream agricultural runoff delivers large quantities of fertilizer, namely nitrogen and phosphorus, to the Everglades. Sawgrass prairie has converted to cattail marsh, where this has occurred, with deleterious effects on organisms and water quality." from:(http://academic.emporia.edu/aberjame/wetland/everglade/everglade.htm)
Humans poach all sorts of endangered animals and the alligator snapping turtle specifically is a concerned species after being hunted so much. Still they are smuggled and sold as pets.
