(d) it is the garden's natural growing medium.​

Answer 1

absorbs and retains water

Answer 2

The correct answer is option (a) it absorbs and retains water.

Explanation:

• We should keep soil well maintained as it absorbs and retains water.
• Soil is the loose surface material that covers most land. It consists of inorganic particles and organic matter.
• Soil provides the structural support to plants used in agriculture and is also their source of water and nutrients. Soils vary greatly in their chemical and physical properties
• The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.
• They include grading or reshaping the ground to lessen steep slopes or shoring excavated areas with wood, concrete, or steel structures.
