3) autotrophic nutrition

heterotrophic nutrition

4)Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.

example:-green plants

5) Autotrophs are the producers in the food chain, they create their own nutrients and energy.

6)Heterotrophic nutrition is a type of nutrition in which organisms depend upon other organisms for food to survive.

7)the process by which green plants turn carbon dioxide and water into food using energy from sunlight.

8)6CO2 + 6H2O → C6H12O6 + 6O2 + 6H2O

(Carbon dioxide) (Water) (Glucose) (Oxygen) (Water)

9)

(1) absorption of light energy

, (2) conversion of light energy into chemical energy,

(3) storage of chemical energy in sugars. Those three events occur in two distinct but interdependent sets of reactions

10)above diagram shown

11) above diagram shown

12)(a) photosynthesis

(b)autotrophs

(c)chloroplast
