Omnivores are organisms that eat both plants and animals. This dietary flexibility allows them to adapt to various environments and food sources. Common examples of omnivores include humans, bears, and pigs. Their ability to consume a wide range of foods helps them thrive in different habitats. In ecosystems, omnivores play a crucial role in maintaining balance. They can help control populations of both plant and animal species, contributing to the health of their environment. By eating a diverse diet, omnivores also support nutrient cycling, which benefits other organisms within their ecosystem.
