Wildebeest, however, are very strong, and can inflict considerable injury even to a lion. Wildebeest have a maximum running speed of around 80 km/h (50 mph). [49] [50] The primary defensive tactic is herding, where the young animals are protected by the older, larger ones, while the herd runs as a group. Typically, the predators attempt to ...
Spotted hyenas usually hunt wildebeest either singly, or in groups of two or three. They catch adult wildebeest usually after 5 km (3.1 mi) chases at speeds of up to 60 km/h (37 mi/h). Chases are usually initiated by one hyena and, with the exception of cows with calves, there is little active defence from the wildebeest herd.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.

The human population exploits and depends on many animal and plant species for food, mainly through agriculture, but also by exploiting wild populations, notably of marine fish. [ 10 ] [ 11 ] [ 12 ] Livestock animals are raised for meat across the world; they include (2011) around 1.4 billion cattle , 1.2 billion sheep and 1 billion domestic pigs .
Kleiber's law describes the relationship between an animal's size and its feeding strategy, saying that larger animals need to eat less food per unit weight than smaller animals. [21] Kleiber's law states that the metabolic rate (q 0 ) of an animal is the mass of the animal (M) raised to the 3/4 power: q 0 =M 3/4
Humans eat various substances for energy, enjoyment and nutritional support. These are usually of plant, animal, or fungal origin, and contain essential nutrients, such as carbohydrates, fats, proteins, vitamins, and minerals. Humans are highly adaptable omnivores, and have adapted to obtain
The 146 extant species of Bovidae are split into 53 genera within 9 subfamilies: Aepycerotinae, or the impala; Alcelaphinae, containing the bontebok, hartebeest, wildebeest, and relatives; Antilopinae, containing several antelope, gazelles, and relatives; Bovinae, containing cattle, buffalos, bison, and other antelopes; Caprinae, containing ...
