Biological relationships refer to the interactions and connections between different living organisms within ecosystems. These relationships can be categorized into various types, such as predation, mutualism, commensalism, and parasitism. Each type describes how species interact, whether one benefits at the expense of another or both benefit from the relationship. In ecosystems, these relationships play a crucial role in maintaining balance and promoting biodiversity. For example, pollinators like bees and butterflies engage in mutualism by helping plants reproduce while obtaining nectar for food. Understanding these relationships helps scientists and conservationists protect ecosystems and the species that inhabit them.
