What types of struggle for existence do you know?

There are three forms of the struggle for existence: intraspecific, interspecific and the struggle with adverse conditions of inorganic nature. The most intense of them is intraspecific struggle, which is especially aggravated with an increase in population density. Interspecific struggle is observed between populations of different species. It can manifest itself in the form of competition for the same types of natural resources or in the form of unilateral use of one species by another – the relationship between the predator and the victim, the parasite and its owner. The fight against adverse physical conditions also plays a large role in the evolutionary changes of organisms. Abiotic factors have a significant impact on the evolution of organisms not only by themselves – their influence can enhance or weaken the intra- and interspecific relationships.
