The term for a certain mode of sustenance based on animal consumption is called carnivorism or being a carnivore. Carnivores primarily feed on other animals, obtaining their energy and nutrients through predation or scavenging. This dietary strategy allows them to thrive in various ecological niches and often influences their anatomical and physiological adaptations, such as sharp teeth or enhanced sensory abilities for hunting. Understanding carnivorism contributes to knowledge of food webs and energy dynamics within ecosystems.
