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 ...
The terms detritivore and decomposer are often used interchangeably, but they describe different organisms. Detritivores are usually arthropods and help in the process of remineralization. Detritivores perform the first stage of remineralization, by fragmenting the dead plant matter, allowing decomposers to perform the second stage of ...
In particular, many different types of material are collected together by currents, and much material settles in slowly flowing areas. A large amount of detritus is used as a source of nutrition for animals. In particular, many bottom feeding animals living in mud flats feed in this way. In particular, since excreta are materials which other ...
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.

There are many modes of feeding that animals exhibit, including: Filter feeding: A form of food procurement in which food particles or small organisms are randomly strained from water. Deposit feeding: obtaining nutrients from particles suspended in soil; Fluid feeding: obtaining nutrients by consuming other organisms' fluids
Living up to seven years, these beautifully decorated shellfish are mild-tempered and shy. Usually found in pairs, these night owls prefer to hide during the day and feed at night. 24. Ramshorn Snails
Tardigrades feed by sucking animal or plant cell fluids, or on detritus. A pair of stylets pierce the prey; the pharynx muscles then pump the fluids from the prey into the gut. A pair of salivary glands secrete a digestive fluid into the mouth, and produce replacement stylets each time the animal moults. [ 3 ]
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.
