THE BIOSPHERE :: essays research papers fc

BiosphereThe biosphere is part of the earth in which life exists. It is 20 kilometers dense from the bottom of the ocean to the lower atmosphere. It consists of three layers the lithosphere, which is the land on the go up of the earth the hydrosphere, which comprises of the water on the earth as well as water vapor in the channelise and the atmosphere, which is made up of the air that surrounds the earth. The living organisms in the biosphere interact and affect each separate in many ways. This is c onlyed a biotic club. There are non-living elements that have an personnel 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 live in special groupings -- for instance - a population consists of all individuals of a type living in a general study. An community is a population located in a certain area living among different species. An ecosystem is a larger m ass of a population, a community, and abiotic factors. Ecosystems can be aquatic or terrestrial. The earths aquatic ecosystem makes up near 75% of the earths surface. This aquatic environment is divided into marine and freshwater environments. The earths profane ecosystem is mainly made up of forests and deserts, which make up for 25% of the earths surface. The place or function of an organism in a community is that organisms function. An organisms post is an area picked by that organism based on physical factors such(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 well as provides the organism with a place to reproduce. In this case, organisms may have the similar habitat, but different niches. There are three types of relationships involving the interactions surrounded by 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 other benefits from the other without damaging or benefiting it), and parasitism* (an intimate association between organisms of tow of much kind especially one of which a parasite obtains from a multitude which it usually injures.) 1.) Mutualism is a relationship where both organisms benefit from their interaction with each other.
