Healthy soil is home to thousands of species of bacteria and other tiny organisms. What benefit do soil organisms provide?

Question

1. They perform photosynthesis for plants.
2. They release water to keep the soil from drying out.
3. They may grow into plants or animals that live on the surface.
4. They are decomposers that return nutrients to the soil.

Answer 1

The correct answer is:

4. They are decomposers that return nutrients to the soil.

Soil organisms, including bacteria, fungi, and other microorganisms, play a crucial role in breaking down organic matter. This decomposition process releases essential nutrients back into the soil, making them available for plants and contributing to soil fertility.
