The correct answer is interspecific competition because it specifically refers to the interaction that occurs when individuals of different species compete for the same resources in an ecosystem, such as food, space, or light. This type of competition can significantly influence the population dynamics and community structure as each species may impact the other's growth, survival, and reproduction.

Interspecific competition is crucial for understanding ecological relationships as it can lead to niche differentiation and evolutionary adaptations over time. For example, two species may evolve different feeding strategies to exploit different parts of the same resource, thereby reducing direct competition and allowing for coexistence.

The other competition types focus on different aspects. Intraspecific competition involves individuals of the same species competing against one another, which can lead to increased competition within the population. Interference competition focuses on direct interactions where one species limits another's access to resources, often through aggression or active exclusion. Exploitation competition refers to indirect competition, where one species consumes resources more efficiently, effectively limiting availability for another species. While these all represent different dynamics within ecological communities, interspecific competition is the one that clearly defines the scenario described in the question.
