The term ecosystem was first coined by Roy Clapham in 1930, but it was ecologist Arthur Tansley, who fully defined the ecosystem concept.

The biological spectrum is made up of all living organisms divided into three domains, coexisting across various levels of biological organization.

The biosphere is the part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life. The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere.

The biosphere is composed of all living organisms. Plants, animals, and one-celled organisms are all part of the biosphere. The biosphere includes all the areas inhabited by living things, like the hydrosphere, which includes all the water; the atmosphere, which includes all the air; and the lithosphere, which includes all the land.

Human species more powerful than others in his ability to manipulate the environment. Man has created new artificial ecosystems - cities, where soil has been covered with concrete and steel. Man also changes weather year round to suit his needs. All this has finally changed the biosphere into a human-dominant environment, called as noosphere. This self-sufficient biosphere is being used by man as a means of resources for himself unmindful of the needs of other organisms.

British botanist A.G. Tansley first introduced the term ecosystem to describe a group of living organisms and its effective environment. Tansley's definition in 1935 referred to the whole system, including not only the organism complex, but also the whole complex of physical factors forming the environment of the biome. 

The biosphere is the global ecological system, integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere.

• It is mostly the climate (temperature and precipitation) in an area, that determines its biome. This is because climate limits the species of plants, that can grow in an area. In turn, the species of plants determine the kinds of animals, that live there. 
• A biome's boundaries are determined by climate more than any other factor. E.g., tundra is colder and has a shorter growing season than other biomes, it has fewer kinds of vegetation. 
• Towards the equator, precipitation becomes increasingly important, producing temperate communities of desert, grassland, and forest in increasing order of precipitation. 
• In the tropical and subtropical biomes, which occur in the equatorial latitudes, there is a relatively smaller range of temperatures during the year, and their variation is also determined by the amount of precipitation. 
• Another important factor is the altitude. Changes in vegetation occur with increasing altitude. 
• Soil is an important factor as it will determine the type of vegetation and biodiversity of that area.
