Answer:
3. When food became covered in microbes, maggots, flies, and rodents: these organisms were caused by tiny microorganisms invading a host organism.
Explanation:

Things like rotting food were thought to give rise to new organisms However, we now know that living things can only arise from other living things. What we are really observing with microorganisms growing on rotting food is that they like to eat it!
