Ecology is defined mainly as a science that deals with the study of the relationship of living organisms, both separately and as part of their communities with the environment. It is closely related to other biological disciplines such as botany and zoology. After all, it has been proven that the direct way of life of each individual animal is closely related and itself affects its environment, its habitat. That is why it is impractical to consider each system separately, because part of the mutual relations will certainly lead to another system, will exist only in these mutual relations of systems and is impossible in their absence.

Step 1
It should be remembered that very complex processes take place in the biosphere, which also require complex consideration. All organisms living on earth have the closest ties with each other, with other populations, as well as with the environment, in which not only living organisms are present, but also inanimate nature. The clearest and most understandable examples of these elements are light, air, water, soil, and temperature.
Step 2
Any changes in the environment will soon affect living inhabitants, for example, various types of animals. So the pollution of water bodies in one area should be understood as an obvious reason for the movement of any animal population to another area. Also, a decrease in the population size may mean an insufficient amount of acceptable food that animals can find in their habitat, or the food available to them in their environment is of poor quality, which means it is not effective for their growth and development.
Step 3
Different populations find different ways out of the prevailing difficult situations for survival. Someone remains in the same territory and continues to cope with the difficulties here, but there are species of animals that prefer to go in search of other territories, more favorable for their existence. But if the territory that suits the population is not ready to accept such a number of these animals, then gradual changes in the environment should be expected. Animals can eat any kind of vegetation much faster than nature is able to restore. Thus, the flora of the area will suffer. If, for example, birds and insects are directly dependent on the flora, then one should expect changes in their habitat. Everything is interconnected in nature. Changes in one place will certainly entail changes in another, and as a consequence, in other places.
