Answer 20

O2 + C6 H12 O6 → H2O + CO2 + ATP

Question 21

Equation:
Photosynthesis:

Answer 21

Carbon + Water → Sugar + Oxygen [ 6CO2 + 6H2O + Sunlight → C6 + H12 O6 + 6O2

Question 22

Respiration:

Answer 22

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Question 23

Nitrification:

Answer 23

2NH3 + 3O2 → 2NO2- + 2H+ + 2H2O [oxidation of ammonia (NH3) to Nitrite 9NO2-)
