What is the next phase of the carbon cycle for the carbon source labeled B? Label A shows a collection of coal, oil and gas. Label B shows a collection of trees and vegetation. Label C shows sky and open atmosphere.

Condensation
Transpiration
Photosynthesis
Decomposition

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
