The importance of animals in nature and the role of plants. Animals in human life

The fascinating world of nature includes everything, from sources of water, soil and ending with such living organisms as plants and animals. The man himself is part of this natural habitat, to which, however, he not only managed to adapt, but which in many ways changed to his needs.

The world of nature

The Earth is a planet that is already about 4.6 billion years old and which, according to the opinion widely spread in science, was due to the Big Bang. Now it is already known that certain forms of life can exist on other planets, but only the Earth can boast of having life on it and such a wealth of flora and fauna.

Great is the significance of nature, plants, animals in particular. Their role in the global ecosystem will be discussed further. It is difficult to imagine how many physical, biochemical, geological and other processes were realized during the existence of our planet. Changes in the earth's surface, climatic changes created the conditions under which the living nature could appear: animals, from protozoa to mammals, vegetation, from grass to exquisite flowers, fungi, various microorganisms such as viruses and bacteria.

The role of the plant community in the universal system of vital activity

Living organisms have a specific gravity in any natural complex. They support the universal cycle of substances and energy, which is necessary for the existence of life. The immediate participants in this process are plants. Green plantations determine not only the appearance of a specific locality and perform an aesthetic function. Their significance lies in the absorption of carbon dioxide and the production of oxygen, without which the existence of animals and humans is impossible. Thanks to photosynthesis, plants are able to produce new organic substances.

In addition, they form soils, the amount of water on the earth's surface depends on them and also the creation of different types of climate. Another big role played by plants in the life of man and most animals - they serve as food. The herbivores feed on greens, and thanks to the gardens and orchards people produce grains and legumes, vegetables and fruits, tea, etc.

Importance of animals in nature

Not only plants, but also animals provide equilibrium in the entire biosphere, affect its dynamic aspect. Animals inhabit all geographical zones and are found in various natural environments: land and air, land, water. Depending on the conditions of life, their appearance, morphology, level of development are different. But each of the representatives of the animal world is important in its own way. The importance of animals in nature is determined by those specific functions that are associated with the natural instincts of these living beings.

So, invertebrate animals (insects, worms, mites, etc.) are able to form the soil. Their positive influence on the properties of the soil cover is manifested in the mixing of fine earth, processing residues from plants, etc. So the nutrient medium creates conditions for other microorganisms, plants. For plants there is also another meaning of animals: in nature it is concluded that animals (bees, birds, etc.) participate in the pollination of flowers and the spreading of seeds of grasses and trees. And most importantly: the number of plants is regulated by herbivorous animals, and predatory, in turn, carry out a natural selection of the latter.

Animals in human life

For whom else are animals vital? As is known, the importance of animals in nature as a whole is undeniable, but a person without them can not live. First, they have always been one of the permanent sources of nutrition. They satisfy the need of the human body for high-calorie proteins, which are involved in many processes of growth and development, as well as in energy production. In food, people use meat like birds and mammals, and invertebrates, most often crustaceans and mollusks. From cattle it is possible to receive milk, which is used in the production of many other products.

Secondly, for the manufacture of warm clothes made of leather and fur, a person also uses animals. Of particular value are species such as arctic fox, sable, nutria, fox, etc. At the same time, now, during the ongoing development of science and technology, the wool of animals can yield several times in quality to things made from artificial fur. The third important point: many large animals people use as assistants in their household. For example, donkeys, bulls, horses, camels, elephants can be tamed for complex jobs: to plow the field, lift and carry a heavy load, transport people and stuff.

Friendship between people and animals

One can not help saying a few words about the importance of animals in human life, not only from the point of view of nutrition, clothing made of fur and labor. It is entirely about other interactions - interaction on an equal footing, as with our smaller brothers. There are so many touching stories about the friendship of man and animals. They give each other affection and care. Such friendship does not lend itself to description, words are not required - it is enough to see how they behave towards each other. Some kind of special non-verbal communication between them. Everyone knows the devotion of dogs that seem to love people unconditionally and endlessly. A four-legged friend will make a company and in a run in the mornings, and will warm on a winter evening, and will meet at the doorstep. Animals brighten up our loneliness.

Some conclusions

Based on the data provided, nature, wildlife, plants for us are simply irreplaceable. Often we neglect them for the sake of our own pleasures and comfort - large-scale deforestation and construction of houses, factories and machines that pollute the atmosphere, a huge amount of debris on the streets and in forest-park areas ... Nevertheless, care and protection of nature should be for us on the first Plan, otherwise we risk ruining ourselves and the whole planet.
