Question

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. planting more trees

Explanation:

1. During photosynthesis, plants take in carbon - dioxide and release oxygen. During respiration, organisms take in oxygen and release carbon - dioxide, thus connecting the two cycles.
2. Understanding the carbon cycle is important because it helps us comprehend climate change. Carbon - dioxide is a greenhouse gas, and changes in the carbon cycle can affect global temperatures.
3. Planting more trees helps reduce extra carbon - dioxide in the atmosphere because trees absorb carbon - dioxide during photosynthesis and store carbon in their biomass.

Answer:

1. The carbon cycle and oxygen cycle are connected through the processes of photosynthesis and respiration. Plants use carbon - dioxide and release oxygen during photosynthesis, while organisms use oxygen and release carbon - dioxide during respiration.
2. It is important to understand the carbon cycle because it helps in understanding climate change as carbon - dioxide is a major greenhouse gas and changes in the carbon cycle can impact global temperatures.
3. One way humans can help reduce extra carbon - dioxide in the atmosphere is by planting more trees as trees absorb carbon - dioxide during photosynthesis.
