Model Answer
  1. Supports living organisms: Soil is home to various living organisms such as decomposers, bacteria, and other life forms that carry out biological activities within it.
  2. Contains organic matter (humus): Soil contains humus formed by the decomposition of organic matter, making it biologically active rather than a mere inert material.

Explanation

The question targets one specific line from the chapter: "The soil is a living system." Examiners expect you to justify this statement using points directly from the text — the presence of living organisms (decomposers, etc.) and the presence of organic/humus content are the two clearest reasons given. Avoid vague answers like "soil has nutrients"; link it explicitly to why soil is living, not just fertile.
