The biosphere is mainly described by the reference of the whole life and living organisms around the Earth. It consists of five levels of organizational structure:
(1) Biomes
The large biosphere is divided into large parts of biomes. Scientists classified biomes into five different types: tundra, grassland, forests, deserts, and aquatic biomes.
(2) Ecosystem
The ecosystem is made up of a biological community and the physical environment. And so it includes both the biotic and abiotic factors. The living things and their physical environment function together as a unit.
(3) The community of Species
A biological community, though, is defined as the assemblage of interacting organisms (either of the same or different species) coexisting in a particular area and time.
(4) Population
All the members of the particular species living in the single habitat are known as Population The population size can vary from a few to thousands of members.
(5) Organisms
The organisms are the living entities of the biosphere.
