The two correct answers are:
A. Plants convert carbon from the atmosphere to sugars through photosynthesis.
B. Cellular respiration uses oxygen from the atmosphere to produce energy and carbon dioxide.
The correct answers are A and B.
A. Plants convert carbon from the atmosphere to sugars through photosynthesis. During photosynthesis, plants take in carbon dioxide from the atmosphere and, with the help of sunlight and chlorophyll, convert it into glucose (sugar). This process removes carbon from the atmosphere and stores it in plants.
B. Cellular respiration uses oxygen from the atmosphere to produce energy and carbon dioxide. In cellular respiration, both plants and animals use oxygen to break down glucose and other organic compounds, releasing energy for their cellular processes. As a byproduct, carbon dioxide is produced and released back into the atmosphere.
These two processes, photosynthesis and cellular respiration, are interconnected and contribute to the cycling of carbon among Earth's systems. Photosynthesis removes carbon from the atmosphere and stores it in plants, while cellular respiration releases carbon dioxide back into the atmosphere. This carbon exchange between plants and the atmosphere is part of the carbon cycle, which plays a critical role in regulating Earth's climate and maintaining the balance of carbon in our planet's systems.
