5 Questions
What are the environmental conditions necessary for microbial growth and reproduction?
Water, chemical elements, gases (nitrogen, oxygen, and carbon dioxide)
What do bacteria, fungi, yeasts, and molds need to produce nutrients, enzymes, and growth factors?
Water, chemical elements, and gases from the air (nitrogen, oxygen, and carbon dioxide)
How do many microorganisms obtain carbon?
From simple compounds such as carbon dioxide and some through the process of photosynthesis
What is the difference between facultative bacteria and non-facultative bacteria?

What are some common sources of bacteria?
Raw food, people, soil, air, and water
