Is competition a cause of extinction?

Yes, competition can be a cause of extinction, particularly when species compete for limited resources such as food, habitat, or mates. When one species outcompetes another, it can lead to the decline or disappearance of the less competitive species. This is often exacerbated by environmental changes and human activities that further alter ecosystems, intensifying competitive pressures. Ultimately, the survival of species depends on their ability to adapt to competition and changing conditions.
