Forest biocenosis structure, description and main factors

Forest biocenosis is a complex of vegetation characteristic of a given geographical continent, characterized by a large part of trees growing in large size, together with the animal world and various inanimate natural factors and relationships existing between them.

The natural forest is the most complex and stable ground ecosystem. It is characterized by vertical stratification, in a fairly straight forest (a layer of crowns, shrub layer, fleece layer). The forest plays an important role in the regulation of water conditions in this area. Flows often occur in deaf areas, and snow and mud avalanches often occur in the mountains.

Determination of forest biocenosis

Forest is a compact plant formation with a predominance of trees and a certain fauna. Depending on climatic conditions, we can distinguish many types of this education that differ in view of both plants and animals. We distinguish between coniferous, deciduous, mixed, tropical, monsoon forests, etc. D. Forest is one of the most important ground ecosystems. Due to the process of photosynthesis occurring in the leaves of trees, oxygen is formed, and carbon dioxide, which has recently causes global warming, is depleted.

Forest biocenosis, by definition of prof. AND. AND. Caspinsky is a dynamic creation of nature in which they are integrated into an inseparable whole system of dependencies, connections and mutual influences: special vegetation with a predominance of wood forms, associated animals and geological substrate, soil, water and climate used by plants and animals.

The main components of forest biocenosis

The main component of forest biocenosis are plants that are manufacturers of organic substances. They are called producers. Consumers of these substances are called consumers. These include predatory and herbivores, birds and insects. Microorganisms, mushrooms and invertebrates, which overwhelm organic waste and bring them to a state of simple mineral compounds, are called gearboxes. This shows that plants are the main link in the ecosystem and food chain.

The structure of forest biocenosis

In all types of forests, individual layers that differ from each other can always be distinguished. These layers differ among themselves depending on the location:

  • the lower tier, which includes grassy plants, mosses, lichens and mushrooms;
  • A undergrowth is shrubs and young trees;
  • The upper tier is formed.
  • Each of the layers creates various habitats, so the fauna and flora lives there, characteristic of it. Species composition of forest biocenosis is due to the type of forest.

    Factors destroying forest biocenosis

    As you know, there are several causes of the destruction of biocenosis. These are anthropogenic and natural factors. The most dangerous human interventions include air pollution, soil, water, excessive deforestation and fires.

    Natural dangers include diseases, epidemics, intensive development of pests.

    The next group of threats is abiotic factors caused by atmospheric and physiographic conditions. However, most of the dangers, one way or another, is associated with human activities.

    The mass appearance of insect-pests of trees is due to a limited number of species of birds that feed on these pests. The absence of birds is usually caused by environmental pollution and often hunting. Changing environmental conditions are caused by climate warming, which is probably causes a person as a result of his activity.

    Forests are called green lungs of the Earth, we must take care of them. Otherwise, we can upset the fragile balance of biological effects that may have catastrophic consequences.
