Quizplus · Accepted Answer

Microorganisms play key roles in the cycling of carbon, nitrogen, and sulfur, all of which are important nutrients for plants. For example, microorganisms help break down organic matter and release carbon, nitrogen, and sulfur in forms that are available for use by plants. Additionally, microorganisms can help fix nitrogen from the atmosphere, making it available for plant use, and can also participate in sulfur transformations that are important for plant growth. Therefore, D is the correct answer.
