Competitive Exclusion: When two or more species compete for the same resources in an ecosystem, one species may outcompete and eliminate another species from that particular niche.
Niche Differentiation: This term describes how similar species evolve slightly different traits or behaviors to occupy different niches within an ecosystem, reducing competition.
Ecological Succession: The process by which an ecosystem changes over time as new species colonize and replace existing ones due to changes in environmental conditions.
