In nature, everything is connected with each other.Animals and plants living in a natural area, make certain the power supply circuit.It represents the uptake by plants sunlight, water and certain inanimate elements and converting them into organic substances.Then these substances and the plants themselves become food for wildlife.Smaller carnivores eat herbivores.The following are scavengers, feeding on decay products.All this makes the sequence and the food chain or supply chain.
for each area of land characterized by a certain food chain.It depends on the representatives of flora and fauna, which are presented in this range.The power supply circuit also includes and microorganisms.Usually the food chain begins with the representatives of the smaller area.For example, in the water, it originates from algae or small single-celled organisms.Then there are grazers: crabs, crayfish, clams, oysters.Plankton in reservoirs plays an important role as a major source of the food chain.
to land the primary source of the food chain are plants.Followed by herbivores and insects: ungulates, rodents, birds, reptiles.Herbivores feed predators and animals feeding on carrion.
Steppe - a territory located in the plain, in the subtropical and temperate zones of both hemispheres.For the characteristic grassy steppes, low-creeping vegetation and few trees.
power circuit in the desert due to the presence of representatives of its characteristic flora and fauna.Among the plants is dominated by feather grass, sagebrush and other prairie grasses.They tolerate drought, do not require large amounts of water.Their autonomic system is arranged so that the main peak of their development falls on the spring.This is the time to create the most favorable conditions.The fauna of the steppe are ungulates, rodents, reptiles and insects.Very often there are squirrels, jerboa, marmots.The family of birds is represented by steppe eagles, bustards, larks and others.
power circuit steppe zone might look like this: Blackberry - Lemming - fox.It is small, consisting of three units of the power supply circuit.Longer can be represented as follows: a snake - the spider - mantis - Grasshopper - grass.In the steppe, there are many food chains.They involve all the animals and plants that live in the area.It is a link that can not be broken or torn.The destruction of at least one level, lead to the disappearance or extinction of other animals.
Recently, the situation with the destruction of flora and fauna has become catastrophic.People with special cruelty victimized innocent inhabitants not only the steppes, but also other natural areas of the planet.Poaching is suppressed by law, but continues to thrive.Environmentalists are sounding the alarm all countries.Unfortunately, return some plant and animal species is no longer possible.They are irretrievably lost.To prevent the extinction of some endangered species, it is necessary to take urgent measures.
Man is one of the links in the food chain.He became a major predator.Therefore, killing plants and animals, endangers humanity, above all, to exist.Disturb the ecological balance of nature, we put its future at risk.Nature is capable of self-regulation by natural selection.But if one interferes with this process, then recover without help it can not.Protect the environment!It is irreplaceable wealth of the land.
