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 ...
Detritivores are animals that feed largely or wholly on detritus. Subcategories. This category has only the following subcategory. ... Coprophagous organisms (2 C, 3 P)
Animals, such as earthworms, also help decompose the organic materials on and in soil through their activites. Organisms that do this are known as decomposers or detritivores . The science which studies decomposition is generally referred to as taphonomy from the Greek word taphos , meaning tomb.
In contrast, from the point of view of organisms using photosynthesis such as plants and plankton, detritus reduces the transparency of the water and gets in the way of this process. Given that these organisms also require a supply of nutrient salts, in other words fertilizer, for photosynthesis, their relationship with detritus is a complex one.
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.
Amphipoda (/ æ m ˈ f ɪ p ə d ə /) is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods (/ ˈ æ m f ɪ p ɒ d z /) range in size from 1 to 340 millimetres (0.039 to 13 in) and are mostly detritivores or scavengers.
For example, Tokunagayusurika akamusi is a species of midge fly whose larvae live as obligate scavengers at the bottom of lakes and whose adults almost never feed and only live up to a few weeks. Most scavenging animals are facultative scavengers that gain most of their food through other methods, especially predation .
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.
