By and large it is the man-made pollutions of waters that get the most attention, and perhaps rightfully so. But what is also important is the overall contamination, or natural quality of water that will help determine the treatments necessary to make a water safe for public consumption.n example of a point source of water pollution is a pipe from an industrial facility discharging effluent directly into a river. An example of a nonpoint-source of water pollution is when fertilizer from a farm field is carried into a stream by rain (i.e. run-off).
Decomposers are consumers that obtain energy by feeding on and breaking down detritus. Detritus is the waste and remains of dead organisms. Animals that eat detritus are often called scavengers.They include earthworms, some rodents and insects, crayfish, catfish, and vultures.The main decomposers are bacteria and fungi.ecomposers are consumers that obtain energy by feeding on and breaking down detritus.

2.Decomposers break down the dead organisms through decomposition while the detritivores consume the decaying organisms. 3.Most decomposers are in the forms of bacteria or fungus whereas the detritivores come in different forms, namely; worms, millipedes, woodlice, dung flies, and slugs in the terrestrial aspect.here should always be decomposers and detritivores in the ecosystem since they are responsible for breaking down decaying substances thus fertilizing the soil where the plants normally grow. SUMMARY: 1.âDecomposerâ is a general term while detritivores are one of the classifications of decomposers.
