Which major cycle is LEAST negatively influenced by an increase in greenhouse gases and why?
A
Carbon cycle, because the greenhouse gas is the major component of the carbon cycle.
B
Phosphorus cycle, because it is a biogeochemical cycle and does not involve the atmosphere.
C
Oxygen cycle, because oxygen can buffer greenhouse gases by binding to it and converting it with hydrogen to water.
D
Nitrogen cycle, because the atmosphere already has very low amounts of nitrogen, and greenhouse gas converts nitrogen into nitric oxide.
