Plant based absorption is just the short carbon cycle. The carbon absorbed by plants returns to the atmosphere when the plant dies - through decomposition, fire, or farts (which is why it’s erroneous to include cow farts in carbon calculations - that carbon came from the atmosphere, and is simply returning).
This is why #biochar is an effective carbon sequestration strategy. The carbon cycle is hacked so carbon absorbed from the atmosphere by plants is turned into a 1000 year stable form that can be added to the soil reaping other benefits. Composting is similar in that some of the carbon destined for atmospheric return goes into the soil instead, but less and less stable than biochar.
