Answer 1

Answer:

answer no 1 Nutrition is the science that interprets the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion.

answer no 2 Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”

answer no 3 For photosynthesis, green plants absorb water and minerals from the soil and use the energy of the sun to synthesize sugars (carbohydrates). The carbon is obtained in the form of carbon dioxide from the atmosphere through stomata

answer no 4 The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

answer no 5 Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

answer no 6 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 bloodstream.

1.ɴᴜᴛʀɪᴛɪᴏɴ?

ᴀɴs:-the food that you eat and the way that it affects your health

2.ᴡhat is the difference between autotrophic nutrition and heterotrophic nutrition?

ans:-Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition

3. raw material of photosynthesis?

ans:-Raw material of photosynthsis are:-

• sunlight from sun
• oxygen from atmosphere
• minerals thought soil
• chlorophyll present in the plant

4. what is the role of acid in our stomach?

ans:-The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

5. what is the function of digestive enzymes?

ans:-Digestive enzymes play a key role in breaking down the food you eat

6.how is small intestine designed to absorb digested food?

ans:-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 bloodstream
