Question

1.what are the differences between autotrophic nutrition and heterotrophic nutrition?
2.where do plants get each of the raw materials required for photosynthesis?
3.what is the role of acid in our stomach?
4. What is the function of the digestive enzymes?
5.how is the small intestine designed to absorb digested food?

Answer 1

Answer:

1) autotrophic nutrition : is the substance that prepare its own organic food from simple materials such as co² erc.

2) hetrotrophic nutrition : is the substance that can't synthesis food for themselves and depends upon other autotrophs

Answer 2

HERE IS YOUR ANSWER

1. Organism prepares its own food. ... Food cannot be prepared from carbon dioxide or water. Green plants and certain bacteria like blue green algae have autotrophic nutrition. All the animals, most bacteria have heterotrophic nutrition.

2. The raw materials required for the process of photosynthesis are carbon dioxide, water and solar energy. The carbon dioxide present in the atmosphere diffuses into the leaf through stomata. Water is obtained from the plant roots.

3. What is the role of the acid in our stomach? Hydrochloric acid plays a major role in the process of digestion. It creates a medium of gastric juice acidic so that the enzyme pepsin digests the protein and kills the bacteria present in them. ... The acid activates the pepsinogen enzyme required to digest proteins

4. Enzymes are essential for healthy digestion and a healthy body. They work with other chemicals in the body, such as stomach acid and bile, to help break down food into molecules for a wide range of bodily functions.

5. The small intestine has millions of tiny finger-like projections called villi. These villi increase the surface area for more efficient food absorption. Within these villi, many blood vessels are present that absorb the digested food and carry it to the blood stream.
