The best example of competition between individuals of the same species is a scenario where multiple individuals of that species are vying for the same limited resources, such as food, water, or nesting sites.
For instance, a group of male deer competing for dominance in a mating season is a clear example. They engage in battles, display aggressive behaviors, and use their antlers to establish hierarchy and secure access to females, all of which demonstrate competition for reproductive success. This scenario highlights the struggles for resources and mates that exist exclusively within the species, making it a classic example of intraspecific competition.
