What is intraspecific competition?

• A. Two members of the same species fight for same resources
• B. Two members of different species fight for same resources
• C. They share resources without conflict
• D. Predation occurs between conspecifics

Answer: (A)

Intraspecific competition is when individuals of the same species compete for resources that are scarce for survival and reproduction, like food, space, or mates. That’s why the best description is two members of the same species fighting for the same resources—they’re competing with each other for what they both need. This kind of competition can influence how a population grows and evolves, selecting for traits that improve access to limited resources. In contrast, competition between different species is interspecific; sharing resources without conflict describes peaceful coexistence or resource partitioning, and predation among conspecifics is cannibalism, not competition for shared resources.
