A. Oceans
To determine the correct answer, we need to understand the processes of respiration and photosynthesis in the carbon cycle.
1. Respiration: This is the process by which organisms, including plants and animals, release energy from organic compounds like glucose. During respiration, carbon dioxide (CO2) is produced as a waste product.
2. Photosynthesis: This is the process by which plants and some other organisms convert sunlight, water, and carbon dioxide into glucose and oxygen. Photosynthesis removes carbon dioxide from the atmosphere and releases oxygen.
Now, let's match these processes with the numbers:
A. 1. Respiration, 2. Photosynthesis
B. 1. Photosynthesis, 2. Respiration
From the explanations above, it is clear that plants perform photosynthesis to convert carbon dioxide into glucose and release oxygen. On the other hand, organisms, including plants, perform respiration to release energy and produce carbon dioxide. Therefore, the correct answer is:
B. 1. Photosynthesis, 2. Respiration
