Difference between biocenosis and biogeocenosis.

The terms "biocenosis" and "biogeocenosis" are used to describe natural complexes that have existed for a more or less long time. What is meant by each of the concepts, and how does the biocenosis differ from the biogeocenosis? Let's find out.


Biocenosis - all objects of living nature located in a specific natural space and interacting with each other under conditions common habitat.

Biogeocenosis is a complexly organized system, the interconnected components of which are the organic community and factors of inanimate nature.


One of the presented concepts is broader than the other. To better understand what is the difference between biocenosis and biogeocenosis, we will analyze each term in more detail.

So, the biocenosis includes exclusively all living things that live within any area of ​​land or water area. And these are different animals and plants, all kinds of fungi and microorganisms. The specific composition depends on what kind of biological creatures the local conditions are suitable for.

For example, vegetation will be part of the forest biocenosis: trees, shrubs, grass growing near the ground. Another component is a rich fauna, which may include birds, beasts of prey and rodents. Various insects, worms, as well as numerous fungi and bacteria also belong to the forest biocenosis.

The organization of the biocenosis is characterized from several sides. First of all, it has a spatial structure, expressed in the ways of placing individual objects (tier of the forest). They also distinguish the species structure, where the emphasis is on the encountered species of living beings and the number of populations of the biocenosis. Another type of structure is trophic, implying food relations between all inhabitants of the territory.

What is the difference between biocenosis and biogeocenosis? To understand this, you should pay attention to the insert "geo", which is in the second term. She reports that in this case, not only the community of interacting organisms (biocenosis) is considered, but also the inextricable connection of these living objects with environmental factors: soil, surface atmosphere, climatic features.

In general, the biogeocenosis is considered as a stable self-regulating system with clear spatial boundaries and the circulation of substances and the movement of energy flows occurring in it.
