Soil organisms, like worms, create tunnels through soil, creating spaces and breaking down materials in the soil. A student claims that soil organisms play an important role for healthy soil that helps plants grow. The student lists information to support the claim in a chart. 1. Soil organisms make it easier for water to move through the soil. 2. Soil organisms change materials into nutrients. 3. Soil organisms help with the removal of soil by water and wind. 4. Soil organisms allow roots to move deep into the soil. Which information from the chart correctly supports the student’s claim?

• 1 and 3 only

• 2 and 3 only

• 2, 3, and 4

• 1, 2, and 4
