Question

5,000,000,000,000,000,000,000,000,000,000. many of those 5 nonillion bacteria help you much more than they harm you. in fact, bacteria have many very important functions for life on earth. in the soil, bacteria help decompose dead organisms and cycle nitrogen through the ecosystem, which plants rely on. what else do bacteria do? bacteria in your digestive system help you digest your food. we even use some bacteria to make the foods we eat. in yogurt, probiotics are often called \good\ bacteria. they ferment the milk. if soil did not have bacteria in it, then choose one option: ○ plants would probably not have enough nitrogen. ○ we probably could not digest our food. ○ plants would probably never die. ○ we could not eat yogurt.

Explanation:

The text states that in the soil, bacteria help decompose dead organisms and cycle nitrogen through the ecosystem, which plants rely on. So if soil had no bacteria, plants would likely lack sufficient nitrogen. The other options relate to bacteria in the digestive system or in yogurt production, not soil bacteria.

Answer:

A. plants would probably not have enough nitrogen.
