Environment
The environment is ecological, it is composed of complex substances and phenomena. Living organisms interact directly and indirectly with the environment. Environment is the total natural environment surrounding organisms (air, light, soil, etc.).

The environment affects the condition of organisms, growth, production, reproduction, diseases directly or as another secondary factor. The environment of each organism consists of many organic and inorganic substances and artificial products resulting from human activities. If an element of the environment is necessary for a certain organism, it does not matter whether you have it or not. An element in the environment can be harmful to the organism.

The specific characteristics of the environment have not changed even during periods of evolutionary production. These include the gravity of the earth, radiation from the sun, the amount of salt in the ocean waters, and the composition of the atmosphere. The movement, humidity, wind, temperature, predators, parasites, comfort of the environment changes both in time and in space, and there is no stagnation in this environment. For example, temperature on Earth has seasons, even during the day, but deep in the ocean, in caves, the temperature is constant. Living in a constant and abundant environment of parasites present in plants, animals and humans, it is variable for predators and depends on the abundance of prey.

Later, the term "external environment" is also used in ecology. The external environment is a sum of natural forces and reality, its substances, energy, distribution, various objective and subjective aspects of human activity, some of which may not be in contact with each other.

The term environment is the very concept of the external environment and is directly equivalent to the object or subject. The concept of environment was introduced by biologist Ya. Yaksol (1864-1944) defined ecology and it as follows: "External world", it surrounds living organisms, influences them through sensory organs, animals' movement organs, and causes the emergence of special characteristics. . Each entity maintains its vitality by creating a complex web, connected to one or another feature of the external environment, like the fibers of a spider's web.
