Living organisms live on the earth everywhere: in the ground-air space, water, soil, and even in other living beings.Each species lives in nature in a particular environment with which it interacts directly.
What is a habitat?In order to answer this question, consider the broader concepts: community biocenosis and biogeocoenosis.Everyone knows that the plants and animals that occupy the homogeneous parts of the territory and interact with each other to form a community.Those, in turn, is linked to all organisms living in a given territory, forming a biocenosis.Interacting with inanimate nature factors (temperature, humidity, lighting and so on. D.), The organisms form a single complex with a circulation of matter and energy, which is called bio- geocenosis.Each species in an ecosystem is fed a certain diet and nutrition is the base for other organisms (food chain), and survives in conditions - abiotic, biotic and anthropogenic - is optimally suitable to him.Habitat, which is an area populated by a particular taxon with clear boundaries, will also be given the right conditions.After all, there are all prerequisites for the prosperity of specific micro-organisms, plants or animals.
The area is called continuous, if the species live in the entire area suitable for its habitat, and meets regularly in its specific field.Sometimes organisms can settle in isolated areas on the border of a specific territory and waters, forming so-called island location.If the habitat is divided into several unconnected sections so that the migration of animals and exchange seeds or spores of the plants are impossible, it is called intermittent, or disjunctive.
A residual is very small in area living area of ancient families, genera and species, which in the past occupied the vast territory called relic, for example, ginkgo biloba or seed.Sagovinikovye.Also, habitat, depending on its value may belong to the so-called cosmopolitans, if it is extensive, and endemic if it is small.
Territory, which is home to certain species of plants and animals, due to the active intervention of man suffer changes, sometimes leading to their complete destruction.However, after the death occurs of flora and fauna that lived in this area, it is populated by new representatives of flora and fauna.To study the resettlement define the boundaries.To do this on the map indicate places where live animals or plants grow specific species, such as the cheetah or the Siberian fir.Such mapping helps to clarify the placement of plant and animal resources, the spread of crop pests and forest land, disease vectors, and so on. D.
On a question about what a habitat, you can answer the following: this is an area with clear boundaries,within which circulated and passes a full cycle of development a particular taxon.The organisms exist here because of the close relationship between environmental factors and other representatives of flora and fauna.
