environment in one way or another affects the living organisms that inhabit it.This effect may be direct or indirect.All elements of the environment that surrounds us affect the living organisms comprise environmental factors.Depending on the nature of origin, they are divided into biotic, abiotic and anthropogenic.
These include all the elements of inanimate nature.These include climatic conditions, light, background radiation, the composition of the soil and water, etc.Thus, for many important plant light and water.Soil conditions affect the character of the vegetation.
Biotic factors - the interaction of living organisms and their influence in the process of communicating with each other.The presence of certain vegetation affects the fauna of this area, and vice versa.Some parasites and bacteria can cause death or reduce the viability of a living organism.Those or other representatives of the animal world can not tolerate certain types of plants.
Anthropogenic factors are manifested as a result of human activity.Recently, they have the greatest impact on the environment.This is due to the development of science and technology and the increase in population.
All three factors can affect living organisms simultaneously to a greater or lesser extent.
The way environmental factors affect organisms depends on the force with which they operate.Since this constant exposure, then under normal conditions, it does not have a destructive influence.This is called the ecological optimum.
If there are deviations in the upward or downward, the vitality of the body decreases.There is a limit of endurance, they can withstand.This figure may differ with respect to each separate or individual.This factor affects the results of natural selection.Those organisms that can adapt to external factors, survive and continue to exist.
For every living organism environmental factors have their importance.The effect of each of them may be different with respect to each individual.For example, some plants can not dispense with light and some mineral compounds.Animals in need of food and water for oxygen.The presence of the latter is vital.
Environmental factors can have an influence on the strength of each other.Some of the more important for living organisms, others are not so popular.
Changing only one of them can influence the condition of all living organisms.
main abiotic factors of the environment - it is light, water and temperature.
Light is important for photosynthesis many plants.Its presence determines the vegetation and, therefore, the presence of animals.
Water is considered as one of the most important elements.Metabolic processes in every living organism are with her participation.The presence of water also affects the populations and the nature of the settlement.
temperature affects many vital processes of organisms.
Anthropogenic factors depend on human activity.But today they are the most influential.When irrational use of resources and environmental pollution takes its change, the disappearance of some living organisms.Sometimes these effects can be eliminated.Some of them do not require human intervention.Nature is able to heal itself.In some cases, people have to help nature to renew its potential.But sometimes nothing can be corrected.
on human factors also affect the environment.It should therefore be more carefully and efficiently organize their activities.
