Question

Which cycle includes bacteria taking gas from the atmosphere and converting it into a material that plants can absorb through root systems?

A. The phosphate cycle
B. The water cycle
C. The nitrogen cycle
D. The oxygen and carbon dioxide cycle

Answer 1

C. The nitrogen cycle

Step-by-step explanation:

In the nitrogen cycle, we have the presence of nitrogen-fixing bacteria, which are essential for this cycle to occur.

This is because, plants are not able to absorb atmospheric nitrogen. So these bacteria, present in the soil, capture nitrogen from the atmosphere and initiate a series of chemical reactions that confers nitrogen in a way that plants can absorb it through their roots.

Answer 2

The nitrogen cycle would be the correct answer.
