Earthworms are soil-dwelling detritivores. Detritivores (also known as detrivores, detritophages, detritus feeders or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces). [1] There are many kinds of invertebrates, vertebrates, and plants that carry out coprophagy.
Detritivores consume organic material that is decomposing and are in turn consumed by carnivores. [16] Predator productivity is correlated with prey productivity. This confirms that the primary productivity in ecosystems affects all productivity following. [20] Detritus is a large portion of organic material in ecosystems. Organic material in ...
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
Decomposers (detritivores) break down dead plant and animal material and wastes and release it again as energy and nutrients into the ecosystem for recycling. Decomposers, such as bacteria and fungi (mushrooms), feed on waste and dead matter, converting it into inorganic chemicals that can be recycled as mineral nutrients for plants to use again.
Carnivores include fishes that feed on zooplankton in the water column (zooplanktivores), insects at the water's surface, on benthic structures, or in the sediment (insectivores), and those that feed on other fish . Fish that consume detritus and gain energy by processing its organic material are called detritivores. Omnivores ingest a wide ...
For example, a marine habitat with five trophic levels could be represented as follows: Herbivores (feed primarily on phytoplankton); Carnivores (feed primarily on other zooplankton/animals); Detritivores (feed primarily on dead organic matter/detritus; Omnivores (feed on a mixed diet of phyto- and zooplankton and detritus); and Mixotrophs ...
Organisms whose diet consists of plant detritus, such as earthworms, are termed detritivores. The community of decomposers in the litter layer also includes bacteria, amoeba, nematodes, rotifer, tardigrades, springtails, cryptostigmata, potworms, insect larvae, mollusks, oribatid mites, woodlice, and millipedes.
