2. moisture
3. air

Answer 2

Factors affecting the growth of microorganisms are:

Temperature

• Temperature affects the rate at which the microorganisms grow.
• It affects their ability to multiply, as well as determines the chances of their survival.
• Extremely low temperatures can freeze the growth of microorganisms and high temperatures can denature them.

Water

• Microorganisms grow well in pure water.
• As the purity decreases, their growth varies.
• There are also microorganisms that require specific types of water to survive.
• Halophiles thrive in seawater since they require a very high concentration of salt.

Radiation

• Certain types of radiation especially ionizing radiations can be extremely harmful to the growth of microorganisms.
• A small level of certain radiation can result in mutation and thus lead to the death of the microorganisms.
• Very high levels can lead to immediate death.
