THE BIOSPHERE :: essays research papers fc

BiosphereThe biosphere is part of the earth in which life exists. It is 20 kilometers thick from the bottom of the ocean to the lower atmosphere. It consists of three layers the lithosphere, which is the land on the surface of the earth the hydrosphere, which comprises of the water on the earth as tumefy as water vapor in the air and the atmosphere, which is made up of the air that surrounds the earth. The living organisms in the biosphere interact and affect each former(a) in many ways. This is called a biotic confederacy. There are non-living elements that deport an effect on living organisms, these are considered abiotic factors. Some examples of abiotic factors are air, temperature, water, soil, light, and minerals. In a biosphere, organisms lie in in special groupings -- for instance - a community consists of all individuals of a type living in a oecumenic area. An community is a population located in a current area living among different species. An ecosystem is a large r mass of a population, a community, and abiotic factors. Ecosystems can be aquatic or terrestrial. The earths aquatic ecosystem makes up about 75% of the earths surface. This aquatic environment is divided into marine and freshwater environments. The earths earthly ecosystem is mainly made up of forests and deserts, which make up for 25% of the earths surface. The role or function of an organism in a community is that organisms function. An organisms role is an area picked by that organism based on sensible factors much(prenominal) as temperature, light, oxygen and carbon dioxide content and biological factors such as food, competition for resources and predators. This niche provides the organism a place to live in. A habitat remains consistent with an organisms niche as closely as provides the organism with a place to reproduce. In this case, organisms may chip in the same habitat, but different niches. There are three types of congenatorships involving the interactions bet wixt organisms. They are mutualism* (mutually beneficial association between different kinds of organisms), commensalisms* (a relation between two kinds of organisms in which one obtains food or early(a) turn a profits from the other without damaging or benefiting it), and parasitism* (an intimate association between organisms of tow of more kind especially one of which a parasite obtains from a host which it usually injures.) 1.) Mutualism is a relationship where both organisms benefit from their interaction with each other.
