What would happen if there were no decomposers in the ecosystem?
There would be no organic nutrients and all the dead plants would ruin the animals habitat.The ecosystem will be fill by plants and animal wastes as there will be no decompositon of waste material.now refer to these points:
1. Decomposers essentially break down the stuff that dies of the stuff produced by living things. So if nothing ever got broken down you would have to walk to school through thick layers of dead stuff and poop. Think of walking through dead dinos and dino poop - ugh! Also, when this stuff is broken down into its parts it lets the materials be used again by new plants and animals and other living things. (A decomposer is an organism, often a bacterium or fungus, that feeds on and breaks down dead plant or animal matter, thus making organic nutrients available to the ecosystem.)
2. The stages of ecological succession are called: Primary and secondary successionPrimary succession and Secondary succession
Primary succession: If the development begins on an area that has not been previously occupied by a community, such as a newly exposed rock or sand surface, a lava flow, glacial tills, or a newly formed lake, the process is known as primary succession.
Secondary succession: trees are colonizing uncultivated fields and meadows. If the community development is proceeding in an area from which a community was removed is called secondary succession. Secondary succession arises on sites where the vegetation cover has been disturbed by humans or animals (an abandoned crop field or cut-over forest), or natural forces such as water , wind storms, and floods. Secondary succession is usually more rapid as the colonizing area is rich in leftover soil, organic matter and seeds of the previous vegetation. In case of primary succession everything has to develop anew.
1. Primary successionbegins with bare rock exposed by geologic activity - example sere: rock -> lichen -> moss -> grass -> shrub -> trees -> oak hickory forest
2. Secondary succession begins on soil from which previous community has been removed (by fire, agriculture, etc.) old field succession - example sere: grass -> shrub -> trees -> oak hickory forestsecondary succession can proceed much faster because the soil has been prepared by the previous community
HENCE WE NEED DECOMPOSERS.
