Answer:

1) Autotrophic nutrition is a mode of nutrition in which an organism prepares its own food with the help of simple inorganic materials like water and carbon dioxide from the surrounding. ... Heterotrophs rely on other organisms for their food whereas autotrophs are independent of any organisms.

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) The main role of acid in our stomach is to kill bacteria and to aid digestion by solubilizing food. ... Stomach acid plays an essential role in the immune system by killing harmful bacteria and parasites that are ingested with food. Stomach acid activates the enzyme pepsin needed for protein digestion.

4)The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.

5) Digestive juice produced by the small intestine combines with pancreatic juice and bile to complete digestion. The body completes the breakdown of proteins, and the final breakdown of starches produces glucose molecules that absorb into the blood.

Answer:

1) Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.
