Freshwater Biome Essay

The Freshwater Biome By Lauren Finnis The freshwater biome is a complex biome that croupe be found all over the world.There atomic number 18 two major fonts of freshwater biomes. The first type is lotic or running which embarrass rivers and streams. Lentic or standing is the second type those include lakes and syndicates. Since this biome is found worldwide, the species that reside in it can vary extensively, but usually it contains several species of weight, plants, and insects.Predation is a way of life in the freshwater biome. It is the main way food and energy argon obtained by well-nigh of the organisms. The plankton, algae, and weeds that produce their own food through photosynthesis are preyen by the smaller fish like the minnows. Then heavy(p)r fish like bass, trout, and pike eat these smaller fish. Finally birds, large mammals, and humans catch the large fish.In the freshwater biome, there are several ex commodiouss of symbiosis. The relationship amidst the freshwa ter sponge and spongillafly is an example of paratism. The spongillafly lays its eggs on the sponge, and then they hatch and unravel off the sponge.Another parasite is the flatworm. It resides in organisms such as the snail and can infect them with lifelessly diseases. There are in addition examples of commensalism in this biome. First is the relationship between small fish and the pond weeds the fish hide between these weeds from larger fish. Another relationship of this type is the peerless between oysters and the mangrove trees. The oyster anchor and protect themselves with the roots of the tree.Finally there are also examples of mutaulistic relationships. For example some small fish enter clean the mouths of larger fish, and in exchange, they may eat whatever they clean out.There are several narrowing factors in the freshwater biome. One of the most important is the availability of sunlight. In areas with little sunlight, photosynthesis can not occur therefore, most plants can not live. Sinceplants are the base of the food chain the whole ecosystem falls apart. Salinity is also a limiting factor. In freshwater areas, there must be a salinity of .05% or less for most organisms to survive. Humans are actually limiting factors also. We destroy and pollute habitats and eat the animals and plants in the biome.Population parsimony in the freshwater biome varies greatly. In rivers or streams, density is usually lower in the faster touching biomes because organisms must fight the current. In lakes and ponds, the topmost areas usually are more dense because there is an ample supply of light for photosynthesis. The highest densities will probably be found in the more temperate areas that organisms can adapt to more easily.The carrying capacity of the freshwater biome depends on the size, location, and availability off light. Biotic potentials in the biome are most likely extremely large. This is because the main organisms are fish, which lay eggs in numerous amounts. Of be given the carry and the biotic potential are rarely met because there are natural enemies and predator. There are also billions of one of the most deadly predator to the biome, humans.
