1) methane

2) carbon dioxide

3) calcium carbonate

4) combustion

Explanation:

1. Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis.

2. Abiotic factors include water, sunlight, oxygen, soil and temperature. ... Sunlight is necessary for photosynthesis.

3. Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic.

4. This carbon dioxide is generated through the process of cellular respiration, which has the reverse chemical reaction as photosynthesis. That means when our cells burn food (glucose) for energy, carbon dioxide is released.
