2. Autotrophic Nutrition
3. Heterotrophs
4. Chlorophyll
5. Photosynthesis
6. Host
7. Insectivorous plants
8. Saprotrophic Nutrition
9. Saprotrophs
10. Symbiotic Relationship​

Answer 1

nutrition is the mode of ingestion and utilisation of food in our body to release energy to carry out various life activities

the plants which can manufacture their own food from simple inorganic substance are called autotrophic plants

plants which depended on some other sources of their nutritional requirement are heterotopic plants

chlorophyll is the green pigment that is present in chlorophyll its use to trap carbon dioxide

the process of food making by plants carbon dioxide and water in the presence of chlorophyll and sunlight

Answer 2

1. Nutrition- Nutrition is the mode of taking food by an organism and its utilisation by the body.

2. Autotrophic Nutrition- The mode of nutrition in which organisms make food themselves from simple substance is called Autotrophs.

3. Heterotrophs- Animals and most other organisms take ready made food prepared by the plants is Cal Heterotrophs.

4. Chlorophyll- The leaves have a green pigment is called Chlorophyll.

5. Photosynthesis- The synthesis of food occur in the presence of sunlight, it is called photosynthesis.

6. Host- The plant on which it climbs is called a host. example: Cuscuta(Amarbel).

7. Insectivorous plants- Insect- eating plants are called Insectivorous plants.

8. Saprotrophic Nutrition- Mode of nutrition in which organisms take in nutrients in solution from dead and decaying matter is called Saprotrophic Nutrition.

9. Saprotrophs- Plants which we Saprotrophic mode of nutrition are called Saprotrophs.

10. Symbiotic Relationship- Some organisms live together and share shelter and nutrition. This is called symbiotic relationship.
