Ecology Part 7: Biosphere and Biome


“If we do not permit the earth to produce beauty and joy, it will in the end not produce food, either”- Joseph Wood Krutch.

A Biome is a portion of the earth that is classified according on the plants and animal living there. Some factors that determine life form found in a biome includes; amount of light, soil type and temperature. Biomes are not ecosystems (Read Ecology Part three of the ecology series for more on ecosystems). Biomes are not ecosystems, but they are usually made up of many ecosystems.  The classification of biomes varies in the scientific community. Everything discussed in the ecology series basically lead up to the Biome. Biomes can be aquatic and terrestrial; all of which makes up the biosphere.

The biosphere is made up of the hydrosphere (refer to water), atmosphere (refer to air) and lithosphere (refer to the solid surface section of the earth). It’s also consist of some other less known spheres. In general, the biosphere is the biological section of the earth systems or the section where life exist. Remember organisms are found in the earth (lithosphere), water (hydrosphere) and air (atmosphere). The exchange of Energy and matter occurs between the biosphere and other spheres. This interaction is very important because it helps to fuelled biogeochemical cycles; which were discussed in Part five of the ecology series.
