Decomposer's role is to break down dead food. They basically eat it, then the dead food or the dead animal gets ground into the ground, and makes the soil good. Like worms, or fungi, mushrooms, etc. Rotten fruit is not really wasted because 1) the decomposers eat it, and 2) it makes the soil good
A food chain is a series of transmission of energy in the form of food when one organism eaten up by another organism. A food web is an interconnection of the food chains.
Decomposers are the organisms, which feed over the dead and decaying parts of the once living organisms. Thus they help in cleaning up of the biological waste from the food web generated after the death of living beings.
The rotten fruit is not truly wasted as the rotten fruit will be consumed by the decomposers. For human beings, the rotten fruit can be considered as the waste and dumped in the garbage but for decomposers it is not a waste, for them it is a source of energy.
The normal microbiota that harbouring an R plasmid will transmit its R plasmid to the normal microbiota because the normal microbiota does not have R plasmid after transmission of R plasmid its increases the resistance capacity of normal microbiota. This is the significance of normal microbiota that harbours an R PLASMID.
Water plants will absorb carbon dioxide for photosynthesis, and some plants will also absorb ammonia (as a source of nitrogen for growth). Aquatic animals like fish and snails absorb oxygen and release carbon dioxide directly into water through specialized structures like gills.
