An animal that can only eat meat is classified as a "carnivore." Carnivores primarily consume animal flesh and may also include fish and insects in their diet. Examples of carnivorous animals include lions, wolves, and eagles. However, some carnivores are opportunistic feeders and may eat non-meat sources when necessary. This classification is crucial in understanding food chains and ecosystems, as carnivores often play a significant role in maintaining the balance of populations among herbivores and other animals.
