on the environment is influenced by various factors.This influence can be direct or indirect.The phenomena of the body or that are its cause, make habitat.Elements of the environment that affect living organisms in any form, referred to environmental factors.Consider some of their species.
environment Environmental factors are divided into two main types.
If they are connected with the influence of inanimate nature and its elements, this abiotic factors.These include air temperature, soil composition, light and other climatic conditions.
If the elements of nature, they are known as "biotic factors of the environment."That is, the interaction of organisms with each other.
There is another kind of factor - anthropogenic.It is the human impact on its environment.
consider in more detail biotic environmental factors.They in turn are divided into several categories.
1. Phytogenic factor involves the impact of the plant.It is characterized by the suppression of the growth of some plants or animals other under the influence of root exudates, the growth of root systems and so on.An example of this is the intolerance of mice smell of elderberry.It is also known that some species do not mix with each other (tulips and cherries).
2. zoogenic environmental factors.The impact on animals of their own kind or representatives of the plant world.So, predators regulate populations of other animals eating them.Parasites sometimes cause death of animals or reducing some of their functions.Individuals of one species together in flocks or herds.This increases the level of some of the processes of life.For example, improved protection from enemies or foraging activity occurs.This factor is called the "effect of the group."
There is also the intraspecific competition, which is also included in the concept of "biotic factors of the environment."
impact of living organisms on each other is most clearly manifested in the interaction between flora and fauna.Herd animals have a mechanical effect on vegetation, trampling it.This is particularly evident in the large gathering of fauna.The destruction of the vegetation cover of the soil leads to a change in its composition and erosion.
3. Mushroom and mikroorganizmennye factors - the influence of bacteria, fungi and other organisms in the environment.
a result of a long period of plant and animal life had been formed close ties between them.Every living organism plays a huge role in the interaction.Biotic environmental factors are a huge system that is not chaotic, but has a certain balance.
intervention in this process leads to irreversible consequences.The destruction of a certain kind of living organisms leads to disturbances in the whole chain.Even the smallest representatives of the environment are essential participants in the process.Insects pollinate plants and are the main factor for their full life.As a result, they get food, and plants - the ability to reproduce.
biotic environmental factors are of great importance.As a result of the evolution of living organisms have learned to adapt to the processes occurring in the environment.The fruits of many plants have all kinds of suckers, hooks or secrete mucus to spread is more fruitful.
can say that all the chains of living organisms invariably lead to deterioration or improvement of the life of a partner or other organism.Violation of the chain results in the death of certain organisms.
