The mechanism of regulation of population size through intraspecific competition for a resource: if the population density is high, it is regulated by an increase in mortality as a result of increased competition. Some individuals die either due to lack of food (herbivores), or as a result of a biological or chemical “war”. Increased mortality leads to a decrease in density. If the population density is low, it is replenished due to an increase in the birth rate due to the renewal of feed resources and weakening competition.
