Humans increase carbon dioxide (CO2) in the atmosphere, and contribute to the carbon cycle by
combustion from driving cars.
planting trees to improve photosynthesis.
conserving energy with alternative energies.
using more solar power electricity.
When deforestation (cutting down trees) occurs in an area, what immediate effect does this have on the water cycle?
More water is returned to the atmosphere by transpiration.
There is less runoff water, but more transpiration.
More photosynthesis occurs, and CO2 begins decreasing.
Less is returned to the air by transpiration.

Oxygen
Carbon dioxide
Water
Ozone
The main result of photosynthesis is
decreased atmospheric nitrogen.
CO2 is removed and captured by plants.
absorbing nitrogen for the plant to use.
global warming caused by CO2 being removed.
Carbon dioxide is returned to the atmosphere primarily by
consumption by animals.
combustion and cellular respiration by consumers.
elimination of waste by animals.
photosynthesis by producers.
