BRAINCAKEIntraspecific Competition
Intraspecific competition is competition between individuals of the same species for the same resources, such as food, water, light, space, breeding sites and mates.
Because individuals of one species have the same niche, they need exactly the same resources, so this competition can be intense. Individuals that are better adapted, for example stronger, faster or better at finding food, are more likely to survive and reproduce.
Intraspecific competition makes populations rise and fall in a cycle:
1. When resources are plentiful, most individuals survive and reproduce, so the population increases.
