Answer 1

Human cannibalism are the one who eats human flesh

Answer 2

Cannibalism is the act of one individual of a species consuming all or part of another individual of the same species as food. To consume the same species or show cannibalistic behavior is a common ecological interaction in the animal kingdom and has been recorded for more than 1,500 species.[1]

Cannibalism, however, does not—as once believed—occur only as a result of extreme food shortage or artificial/unnatural conditions, but could also occur under natural conditions in a variety of species.[1][2][3]

Cannibalism seems to be especially prevalent in aquatic ecosystems, in which up to approximately 90% of the organismsengage in cannibalistic activity at some point in their life cycle. Cannibalism is also not restricted to carnivorous species, but can also be found in herbivores and detritivores.[2]
