Contaminant compounds are transformed by living organisms through reactions that take place as a part of their metabolic processes. Biodegradation of a compound is often a result of the actions of multiple organisms. Bioremediation can be effective only where environmental conditions permit microbial growth and activity.
#Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph. The enzymes convert the detritus into simpler molecules, which are then absorbed by the cells to feed the organism

2. The light wavelength range is needed for PAR is 400 nanometer (nm) to 700nm.
