Answer 2

Answer:

1. Components of Air - Nitrogen, Oxygen, Carbon Dioxide, Water Vapour and Other Gases. ... The Composition of Air: Air is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and other gases in meager amounts. Water vapour is also a constituent of air in varying amounts along with dust particles.
2. The process by which a living being utilizes the food to get energy is called respiration. Respiration is an oxidation reaction in which carbohydrate is oxidation to produce energy.
3. the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
4. It is defined as the separation process in which solids are separated from the liquid. All the solids settle down at the bottom of a beaker and on top, a clear layer of liquid is Obtained.
