Answer:
this is a TRUE statement.
Step-by-step explanation:
Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures, pH, and atmospheric gases because although microbes are widespread in their occurrence,they are found almost everywhere,in the air,water,soil,food,decaying matter,oil deposits,in plants etc.
but their number and their types vary according to the locality and environmental conditions.
Although, some microbes are always present and contribute towards natural flora BUT besides this others are present in specific environments such as some in hot springs bearing very HIGH TEMPERATURE RANGES for example: Thermus aquaticus.
some of them inhabit the acidic or alkaline soil feeding on HUMUS.
Most of the microbes prefer ATMOSPHERIC GASES i.e some require oxygen for their survival .For example: Pseudomonas.
some don't require O2 for survival i.e Spirochete.
IN SHORT, most of the microbes have preferences for various environmental conditions.
