Explanation:-

The primary mechanism allowing trees to pull water from deep within the ground is:

  • Mineral water: Refers to the composition of water and its dissolved minerals, not the mechanism of transport.
  • Capillary action: This is the key process. Capillary action involves the movement of water through the narrow tubes (xylem) within the tree. It is driven by the adhesive forces between water molecules and the walls of the xylem vessels, and the cohesive forces between the water molecules themselves.
  • Photosynthesis: This is the process by which trees convert light energy into chemical energy, but it does not directly relate to water transport from the ground.
  • Wood nature: The characteristics of wood affect water transport efficiency but do not explain the transport mechanism.

Therefore, trees pull water from the ground primarily due to the property of capillary action is capillary action
