Ecological factors






 

One of the major concepts of ecology is a habitat.
Wednesday - is a set of factors and elements that affect the body in its habitat.
Any living creature lives in a complex, ever-changing world, constantly adapting to it and adjusting their livelihoods in accordance with its changes.

Living organisms exist as open, sliding systems, which are stable at inflow thereto energy and information from the environment.
On our planet, living organisms have mastered the four key areas of data, each of which is characterized by a set of specific factors and elements that affect the body.
Life originated and spread in the aquatic environment. Later, with the advent of photosynthesis and, consequently, of free oxygen in the water first, and then into the atmosphere, living organisms " left" on land, air captured medium settle soil.

With the advent of the biosphere as a part of the layers of the Earth inhabited by living organisms, it has become another medium with a certain combination of specific - biotic factors acting on the body.
Adaptation to the effects of environmental factors is called adaptation.

Ecological factor - the element of habitat that can have a direct impact on the living body of at least one of the stages of individual development.
All environmental factors are divided into biotic, abiotic and anthropogenic.

Biotic factors - are all possible influence that is experiencing a living organism from the surrounding living beings.
Everybody is constantly experiencing the direct or indirect influence of living beings come into touch with the representatives of their own species and other species - plants, animals, microorganisms, it depends on them and himself to influence them. For example, the plants during photosynthesis release oxygen for breathing animals, and animals provide entry into the atmosphere of carbon dioxide, without which plants cannot carry out photosynthesis.

Action biotic factors can be both direct and indirect, to use a change in the environment, such as the changing composition of the soil under the influence of bacteria or changes in the forest microclimate. Surrounding the organic world - part of the habitat for all living beings.

Reciprocal links between different types of organisms form the basis of the existence of populations, biogenesis and the biosphere as a whole.

Abiotic factors - it affects the body elements of inanimate nature (temperature, light, humidity, composition of air, water, soil, natural background of Radiation Earth, terrain, etc.).

The most important abiotic factor is the solar radiation, which affects photosynthesis, creation of biomass plants, which depends on the presence of life on Earth.

Water is also an important abiotic factor. For the normal life of plants and animals must constantly maintain a balance between consumption of water and its evaporation.

Anthropogenic factors - factors that caused by human impact on nature.
Human activity on the planet should be allocated in a special force exerted on the nature of both direct and indirect effects. For direct exposure include consumption, reproduction and human settlement as a separate species of animals and plants, and the creation of as many as biocenose. The indirect effect is achieved by changing the habitat of organisms: the climate regime of rivers, land and other state.

According to another classification, environmental factors shared:
- On a regular basis - periodic, changing the force of impact in relation
with the time of day, season of the year or the rhythm of the tides in the ocean;
-Irregular - periodic, catastrophic events;

- Changes in weather conditions in different years, storms, heavy rains, floods, etc.
