Question

1. plants are an important part of cycling carbon in the atmosphere. (5 points)

a. what role does photosynthesis play in the carbon cycle? (2 points)
b. what would happen if we cut down all the trees? (3 points)
a. |

Explanation:

A.

Photosynthesis is the process by which plants use sunlight, carbon - dioxide and water to produce glucose and oxygen. In the carbon cycle, it takes in carbon - dioxide from the atmosphere and converts it into organic carbon compounds, thus reducing the amount of atmospheric carbon - dioxide.

B.

If all trees are cut down, there would be less photosynthesis occurring. This would lead to an increase in atmospheric carbon - dioxide levels as there are no trees to absorb it. Also, deforestation can lead to soil erosion, loss of habitat for many species, and disruptions in the water cycle.

Answer:

A.

Photosynthesis takes in carbon - dioxide from the atmosphere and converts it into organic carbon compounds, reducing atmospheric carbon - dioxide levels.

B.

Atmospheric carbon - dioxide would increase, there would be soil erosion, loss of habitat, and water cycle disruptions.
