'The Great Barrier Reef' is considered as a biome. Since biomes are climatically and geographically defined as contiguous areas with similar climatic conditions on the Earth, such as communities of plants, animals, and soil organisms, and are often referred to as ecosystems. 'The Great Barrier Reef' is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres.

In ecology, a community or biocoenosis is an assemblage or associations of populations of two or more different species occupying the same geographical area and in a particular time. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time. 

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.

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

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.
