Scavenger is the organisms the break apart the dead and also decayed matter into smaller particles. In contrast, decomposer is together organisms that further break-down or decompose the dead matter (dead plants and animals). Together a result, they carry out nutrients come the floor by producing commodities such as nitrogen, phosphorus, calcium.

You are watching: What is the difference between scavengers and decomposers

Therefore we deserve to say the scavengers room the one that initiates the intake of the dead matter and the decomposers finish it, and carry out nutrients earlier to the soil; lock both are connected with the third trophic level food web.

Scavengers can be insects, birds, worms, fishes and also crabs, if decomposers deserve to be bacteria, fungi, invertebrates favor earthworms, millipedes. Scavengers and Decomposers play an essential role in decomposing the dead and also decay plants and also animals, which is beneficial for the ecosystem.

Decomposition is critical natural procedure which is necessary to keep the environmental balance; because through the decomposition the dead organisms again gives ago the nutrient to the environment that has been utilised through it and thus the procedure of recycling go on.

However, this contents is about the differences between the scavenger and decomposer, i m sorry we will be going v by discussing them in the comparison chart, through a quick description, similarities mutual by them, and key differences ~ above them.

Definition that Scavenger

Scanvenger is such animals that feeding on dead and decay pets that have passed away apart from predation. These (scavenger) are likewise known as carrion-feeder or detrivores. Organisms like, carrion beetles invest their lives on decomposing dead pet matter. This beetles start decomposing the body, after entering into it.

Generally, scavenging is the procedure assign quiet the carnivores feeding upon animals, however it is also related come the herbivorous feeding. Scavenging disclosure the shortcomings in the accessibility of food sources in the environment; it is affected by temperature, habitat, seasons and also biotic as well as abiotic factors.


By eat the essential matters, and thus breaking down on the particles right into smaller particles, lock are valuable in cultivating the handle of dead bodies. Castle consume only dead organisms the have passed away to some or the other reason except them being eliminated by one more animal.

Scavengers deserve to be facultative or obligate; most of the animals are facultative scavengers. In this (facultative) kind of scavenging the scavengers, obtains their food through predation; although obligate scavenging is rare as it is tedious job-related to discover carrion without making use of energy. Scavenging is rather threatening also, together they directly or indirectly might spread disease among animals.

Earthworms, Vultures, Crow, Carrion Beetles, Termites, are the few examples that the scavenger.

Definition the Decomposer

Decomposers consume dead materials, choose dead animals, plants, faeces, animals carcasses and wood. Decomposers are biologically known as saprotrophs. They space the members of the cleaning crew the Earth’s. Together without lock waste materials like dead insects, animals, plants and also its leaves would have actually been gathered everywhere, and we even can’t imagine that situation.

The significant fact is that, ~ decomposing, these (decomposers) carry out nutrients come the major producers prefer algae and plants. ~ the role of scavengers, that break the substance into smaller particles, there reach the decomposers which rest the much more complexed organic products into an ext simple or elementary school substances; carbon dioxide, water, calcium, nitrogen and phosphorus. These are materials that a plant requires for its growth.


Decomposers deserve to be specialised or generalised, specialty one feeding on details kind of dead organisms, when generalised one may feed on various organisms. Biology such together protozoa, bacteria, and fungi space categorised together decomposers; also invertebrates prefer millipedes, earthworms, and termites are detritivores.

In the forest area, some fungi choose mushrooms, room the far-reaching decomposers, as they carry out not save chlorophyll (for do its own food), rather they extract the nutrients from the dead plants and also materials, which castle decompose with the assist of specific enzymes.

Key Differences between Scavenger and also Decomposer

Upcoming points are significant to obtain the clean differences between the two type of organic cleanser existing on Earth, which space scavenger and decomposer:

Such organisms that feed on dead and decay animals are well-known as a scavenger. In contrast, such organisms and also invertebrates that malfunction or decomposes the organic matter into the simplest type are known as a decomposer.Generally, scavenger belong come the kingdom: Animalia, conversely, decomposers belong to Fungi, Monera and Animalia.Scavengers are additionally known together ‘Detritivores‘, and also decomposers are also known as ‘Saprotrophs‘.Scavengers are involved in decomposition by breaking down the complexed material into a simple one, when decomposer finish the procedure of decomposition by totally decomposing the simple particles right into elementary one so that it can be exit nutrients earlier to the environment.Insects, worms, birds, fishes and crabs space the examples the the scavengers; Bacteria, fungi and also earthworms room the examples of the decomposer.


Scavenger and also decomposers are well-known to feed on dead and also decay matter.Both species of organisms decompose or break down the organic product into much easier forms.Both pat a far-ranging role in one ecosystem nad known for recycling the nutrients right into the environment.

Scavengers and decomposers are recognized for decomposing the necessary matter, i beg your pardon dead and decaying plants and also animals, and in return, they provide nutrients come the soil. In this way, they are helpful and also much-needed organisms for the ecosystem, as they occupational as the organic cleanser for the land and in water too.
