Scavengers are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators. [1] While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. [2] Scavengers play an important role in the ecosystem by consuming dead animal and plant ...
Important aspects of group living include the frequency and type of social interactions (egoistic, cooperative, altruistic, revengeful) between individuals of a group (social life), the group size, and the organization of group members in the group. [citation needed] Terminology of animal groups also varies among different taxonomic groups.
Many invertebrates, such as the carrion and burying beetles, [6] as well as maggots of calliphorid flies (such as one of the most important species in Calliphora vomitoria) and flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains.

These insects do not feed directly on the decomposing remains or its fluids, but are considered to be the second most forensically important ecological role. [ 3 ] [ 7 ] Predators of necrophagous insects include species from the Coleoptera families Silphidae (carrion beetles) and Staphylinidae (rove beetles). [ 3 ]
A slug, Arion vulgaris, eating a dead individual of the same species. Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. [1] Human cannibalism is also well documented, both in ancient and in ...
The trophic level of an organism is the position it occupies in a food web. Within a food web, a food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain.
Cannibalism was a routine funerary practice in Europe about 15,000 years ago, with people eating their dead not out of necessity but rather as part of their culture, according to a new study.
Necrophages are organisms that obtain nutrients by consuming decomposing dead animal biomass, such as the muscle and soft tissue of carcasses and corpses. [ 1 ] [ 2 ] [ 3 ] The term derives from Greek nekros , meaning 'dead', and phagein , meaning 'to eat.' [ 1 ] Mainly, necrophages are species within the phylum Arthropoda ; however, other ...
