What happenes when organisms have a similar niche?

When organisms have a similar niche, they compete for the same resources, such as food, shelter, and mates. This competition can lead to various outcomes, including competitive exclusion, where one species outcompetes another and drives it to extinction in that niche, or resource partitioning, where species adjust their behaviors or diets to minimize competition. Over time, this can result in evolutionary adaptations and the diversification of species. In ecosystems, such dynamics can influence biodiversity and community structure.
