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 ...
Further trophic levels are numbered subsequently according to how far the organism is along the food chain. Level 1 Plants and algae make their own food and are called producers. Level 2 Herbivores eat plants and are called primary consumers. Level 3 Carnivores that eat herbivores are called secondary consumers. Level 4
Therefore, an organism can be both a detritivore and a decomposer. While there are also purely physical processes, like weathering and ultraviolet light, that contribute to decomposition, "decomposer" refers only to living organisms that contribute to the process, whether by physical or chemical breakdown of dead matter.
Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eaters (or scavengers ) include crows , vultures , humans , hawks , eagles , [ 1 ] hyenas , [ 2 ] Virginia opossum , [ 3 ] Tasmanian devils , [ 4 ] coyotes [ 5 ] and Komodo dragons .
The decomposition of food, either plant or animal, called spoilage in this context, is an important field of study within food science. Food decomposition can be slowed down by conservation. The spoilage of meat occurs, if the meat is untreated, in a matter of hours or days and results in the meat becoming unappetizing, poisonous or infectious.
An example is the koala, because it feeds only on eucalyptus leaves. Primary consumers that feed on many kinds of plants are called generalists. Secondary consumers are small/medium-sized carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers.

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 ...
