Question

what impact can deforestation have on the water cycle? carbon dioxide is released into the air as trees are burned. the amount of nitrogen - fixing bacteria increases. transpiration declines. photosynthesis increases, thereby increasing the amount of carbon dioxide in the air.

Explanation:

Trees play a role in transpiration (the process of water movement through a plant and its evaporation from aerial parts, like leaves). Deforestation reduces the number of trees. With fewer trees, the rate of transpiration (which is part of the water cycle) will decline.

• The release of carbon dioxide when trees are burned is related to the carbon cycle, not the water cycle.
• The amount of nitrogen - fixing bacteria is related to the nitrogen cycle.
• Photosynthesis taking in carbon dioxide (not increasing carbon dioxide in the air as stated in the last option) is related to the carbon cycle.

Answer:

Transpiration declines.
