Non-made objects and objects of the Universe belong to the natural world, which is subdivided into living and inanimate. The ability to distinguish one area of nature from another is formed in students from the elementary grades. This is considered to be one of the most difficult topics in natural history.
The world around us, not created by man, is called nature. She is the main object of the study of science. Most of the natural sciences are engaged in the study of objects of inanimate nature. Biology studies wildlife (this term translated from Greek means the science of life). Biology is a whole complex of sciences about living nature (botany, bacteriology, zoology, anthropology).
Interest in the study of wildlife objects arose in the primitive era and was associated with human needs for food, medicines, clothing, housing, and so on. But only in more advanced civilizations were people able to purposefully study living organisms, systematize and describe them. Although according to various scientists, from 2 to 10 million species of living organisms live on Earth, less than 2 (about 1.9 million) have been openly and described so far.
The objects of wildlife include animals, plants, fungi, bacteria and viruses, as well as humans. Nature can exist without man. This is evidenced by uninhabited islands and astronomical objects (Sun, Moon).
The world of inanimate nature is characterized by stability and low variability (if we talk about the scale of human life). Man is born, lives and dies, but the mountains remain the same as they were millennia ago, and as in the time of Aristotle, the planets still revolve around the Sun.
Inanimate nature is called the entire set of objects that appeared without human assistance and consisting of a field or substance.
These are air, planets, stones, water, etc.
Living organisms are distinguished from non-living bodies by a more complex structure. To maintain vital activity, objects of living nature receive energy from the outside and, to one degree or another, use solar energy. In addition, they have the ability to actively move, overcome resistance, and respond to their environment. For example, if you push an animal, it will attack or run away, unlike a stone, which will only passively budge. All living things can breathe, grow, develop, reproduce and die. Although far from all objects of living nature, all of the listed signs are clearly expressed. For example, plants practically do not move and it is difficult to see how they breathe with the naked eye. And many animals in captivity lose their ability to reproduce. But, nevertheless, they have other signs of representatives of living nature.
