<h2><u>Answer:</u></h2>
The 4 principle requirements for microorganisms survival are:
1) Food
2) Moisture
3) Warmth
4) Time
There are microscopic organisms that can develop in cold temperatures and some that blossom with warm temperatures.
A few bacteria go after the other microscopic organisms for survival. Different microscopic organisms get by getting supplements from dead items. Some microorganisms use photosynthesis to make their nourishment.
