Answers
Answer 1 :- Autotrophic Nutrition
(i). Food is prepared from CO2, water and sunlight. (ii). Chlorophyll is required. (iii). All green plants and some bacteria have this type of nutrition. (iv). Food is generally in daytime.
Heterotrophic Nutrition
(i). Food is obtained from other organisms. (ii). Chlorophyll is not required. (iii).All animals and fungi have this type of nutrition. (iv). Food can be obtained at all time.
Answer 2 :- The Raw materials required for photosynthesis are carbon dioxide and water. Plants (terrestrial) get carbon dioxide from environment and water from the soil. Aquatic plants obtain CO2 that is present in dissolved from in water. Water is simply absorbed by the parts of the plant submerged in water.
Answer 3 :- Stomach acid play an essential male in the immune system by killing harmful Bacteria and Parasite that are ingested with food.
Answer 4 :- Digestive Enzymes helps in digesting complex food materials into simpler molecules for absorption by the body. During digestion of food, different parts of the alimentary Canal produces different digestive enzymes that helps in digestion of different components of food.
Answer 5 :- The Inner Lining of the small intestine has numerous villi (small thin parts that stick out from some surfaces on the inside of of the body) which increase the surface area for absorption. The Villi are richly supplied with blood vessels which take the absorbed food to each an every cell of the body.
