Meateaters

Meat-eaters is a term used to describe organisms that obtain a significant portion of their energy and nutrients from animal flesh. In biology, it is often treated as synonymous with carnivore, especially when referring to species that primarily prey on other animals. Some definitions distinguish obligate carnivores, which rely almost entirely on animal tissue, from facultative carnivores, which can subsist on non-animal foods but prefer meat when available.

In ecological contexts, meat-eaters occupy higher trophic levels as secondary or tertiary consumers. Predators such as big cats, canids, birds of prey, and many aquatic mammals are classic examples. Scavengers and kleptoparasites may also be described informally as meat-eaters, though their diets include non-meat items.

In human nutrition, the phrase "meat-eater" usually refers to people whose diets include meat. It contrasts with vegetarians and vegans, and with dietary patterns that emphasize plant foods. Among meat-eaters, there is substantial variation in how much meat is consumed and what kinds—red meat, poultry, fish, and processed meats—with accompanying debates about health and ethics.

Environmental considerations are often linked to meat-eating, given that meat production affects land, water use, and greenhouse gas emissions. Sustainability discussions frequently consider dietary shifts toward reduced meat consumption, diverse protein sources, and better farming practices.
