Question

1. where is carbon found in the environment? a. only in the oil b. only in the ocean c. in the atmosphere, oceans, soil, and living things d. only in plants 9. what is one effect of adding too much carbon dioxide to the atmosphere? a. more rainfall b. climate change c. more oxygen produced d. less sunlight 10. how do animals get carbon in their bodies? a. by breathing oxygen b. by eating plants or other animals c. by drinking water d. by photosynthesis open - ended questions: answer the following questions in complete sentences. 11. how are the carbon cycle and oxygen cycle connected? 12. why is it important to understand the carbon cycle? 13. describe one way humans can help reduce extra carbon dioxide in the atmosphere.

Explanation:

1. Carbon is present in the atmosphere as carbon - dioxide, in oceans as dissolved carbonates, in soil as organic matter, and in living things as a key element of organic compounds. So the answer is C.
2. Adding too much carbon dioxide to the atmosphere causes climate change due to the greenhouse effect. So the answer is B.
3. Animals get carbon in their bodies by eating plants or other animals which contain carbon - based organic compounds. So the answer is B.
4. The carbon cycle and oxygen cycle are connected because plants take in carbon dioxide during photosynthesis and release oxygen, while animals take in oxygen during respiration and release carbon dioxide.
5. Understanding the carbon cycle is important because it helps us understand climate change, as carbon - dioxide is a major greenhouse gas. It also helps in managing ecosystems and developing sustainable practices.
6. One way humans can help reduce extra carbon dioxide in the atmosphere is by planting more trees. Trees absorb carbon - dioxide during photosynthesis.

Answer:

1. C. In the atmosphere, oceans, soil, and living things
2. B. Climate change
3. B. By eating plants or other animals
4. Plants take in carbon - dioxide and release oxygen during photosynthesis, animals take in oxygen and release carbon - dioxide during respiration.
5. Helps understand climate change, manage ecosystems and develop sustainable practices.
6. Planting more trees.
