The scientific term for the relationship between two species that rely on each other is mutualism. In this type of interaction, both species benefit from the relationship, enhancing their chances of survival and reproduction. A classic example of mutualism is the relationship between pollinators and flowering plants, where pollinators obtain nectar while assisting in plant reproduction. Mutualistic relationships play a crucial role in ecosystem dynamics, promoting biodiversity and contributing to the stability and productivity of ecological communities.
