1.when viruses are outside from the body they are considered as non living but as soon as they enter inside human body or the host , they become living and perform all there metabolic function
2.fermentation is a process of division in the bacteria in the yeast cell through which divide in the absence of oxygen i.e anerobic respiration ....... it is very useful in the processes of formation of cheese and beer factories etc.
3.microorganisms are also called as the scavengers on the earth as they are responsible for the breakdown of the complex compound present in the body of the Dead animals all the plants and and they convert these complex compound into the simplest form and hence they act as the cleaning factor in the environment
