Answer 1

Answer: The answer is C.

Explanation: Soil includes 40-45 percent inorganic matter, 5% organic matter, 25% water, and 25% air. The right combination of air, water, minerals, and organic matter is essential for plant life to thrive. Microorganisms (both dead and alive) and decaying plants make up humus, the organic stuff in soil.
