1-water; 2-nitrogen
1-water; 2-nitrogen

1-oxygen; 2-carbon dioxide
1-oxygen; 2-carbon dioxide

1-nitrogen; 2-oxygen
1-nitrogen; 2-oxygen

1-carbon dioxide; 2-water

Answer 1

The labels likely represent the gases involved in the processes of photosynthesis and cellular respiration. In photosynthesis, plants take in carbon dioxide and release oxygen. In cellular respiration, organisms take in oxygen and release carbon dioxide. Therefore, the appropriate labels would be:

**1-oxygen; 2-carbon dioxide**

So, the correct response would be:

**1-oxygen; 2-carbon dioxide**
