Answer 1

The process used to remove impurities from water is called - (d) Sedimentation .

The method is used by plants for making their food - Photosynthesis .

Answer 2

Answer:

answer is option (d) sedimentation.

sedimentation-

Sedimentation is the process of separating small particles and sediments in water.

This process happens naturally when water is still because gravity will pull the heavier sediments down to form a sludge layer.

However, this action can be artificially stimulated in the water treatment process.

The leaves have a green pigment called chlorophyll. It helps leaves to capture the energy of the sunlight. This energy is used to synthesise (prepare) food from carbon dioxide and water. Since the synthesis of food occurs in the presence o f sunlight , it is called photosynthesis.
