Does the struggle for existence operate in the fields, does it extend to the breeds of animals raised on farms, in fur farm farms, etc.

The struggle for existence is always going on with all living organisms. In the fields, not only insects fight among themselves for food. They fight for existence with various other animals that eat them. Insects are dying out from the action of poisons. Even the plants themselves are fighting for existence. An intraspecific, interspecific struggle occurs immediately, as well as a struggle with natural factors. On farms, there is mainly intraspecific struggle between animals. Although the action of parasites can be considered a struggle between species.
