scavengers and decomposers both feed on dead organism. why have they been grouped separately?
Answers
scavengers means the birds which eat the garbage ( waste )
decomposers means the micro organisms which live in soil
these both feed on dead and decaying organisms so they are grouped differently

Scavenger
Scavenging is a feeding behaviour in which an animal feeds on either dead animal or dead plant matter. Scavengers are the animals with scavenging habits. Scavengers’ role is vital for the ecosystem as they contribute to the decomposition, while decomposers and detritus feeders are responsible for completing the process. Scavengers do not spend energy to kill their prey, but they sense the smell of food on which they can feed. Vultures, Burying beetle, Raccoons, Jackals, and Hyenas are some prime examples for animal scavengers. Termites and earthworms are good examples for plant scavengers. While the scavengers act on the dead animals and plants, they break them in to small pieces of organic materials. Thus, scavengers start the decomposing process. In addition, big helpers for the decomposition process are the scavengers, while detritus feeders are the small helpers.
Decomposer
Decomposition is a process that small organisms act on dead plants and animals biomass to convert those into molecular levels. Decomposers are the organisms that contribute to the decomposition process. Fungi are the primary decomposers in a forest, while bacteria are also good examples. They are microscopic more often than not. However, the dead matter has to be exposed for bacteria to be able to act upon, while fungi can decompose any dead biomass because of their penetrability. Apart from that, enzymes to decompose lignin in wood are present only in fungi. Decomposers release the organic and inorganic molecules in the form of nutrients for the plants and animals. This process is vital for the recycling of the resources inside an ecosystem.
