Introduction The factors discussed in this section constitute an inclusive, rather than exclusive, list of intrinsic, extrinsic, and other factors that may be considered when determining whether a food or Different organisms react to their environment in different ways. Every organism has a minimal, maximal and optimal pH for growth.Some organism can grow better at low pH or acidic pH, some can grow in alkaline pH and while other grow at somewhat neutral pH.pH influence both the growth rate and types of organism that will predominant the food. There are large number of varied factors which contribute to the growth of entrepreneurship. Bacterial growth under nutrient-rich and starvation conditions is intrinsically tied to the environmental history and physiological state of the population. Maintaining work equipment and the physical state of a building is important, but there are potential threats lurking in a company’s infrastructure that are too small for the naked eye to see.
