Answer 9

Aerobic respiration
This is carried out by every licking organism- Animals and decay

Question 10

Recite the carbon cycle ?

2. Animals eat plants and respire to release it back into atmosphere
3. Plants and animals die and turn into fossils
4. These are then burned and released back as carbon through combustion
5. Respiration or decay or dying organism also release carbon dioxide back into the atmosphere
