What relationship can there be between organisms of the same species?

Basically, organisms of one species have a neutral effect of one on one. This type of relationship is called neutralism. But this is not always the case. There can be enmity between two colonies of ants and they will kill one one, although they belong to the same species. In addition, there can be symbiosis between representatives of the species – a mutually beneficial relationship. Also, organisms can badly influence and interfere with other members of the species. This type of relationship is called antibiosis. The main subspecies of antibiosis, characteristic of any species, is competition.
