When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
In some part of the stems, some photosynthesis may also occur.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Plants open its stomata to avoid losing too much water.

To transform atmospheric CO2 into organic molecules, plants can use the energy from
As plants respire, they release
Almost half of the total biomass of a tree may be allocated to the roots.
Carbon capture is performed by the green parts of plants via photosynthesis.
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in air temperature.
the changes in light.
the changes in soil temperature.
Transpiration decreases as air becomes drier.
The effect of light on photosynthesis has a clear saturating pattern: more light results in more photosynthesis but eventually leaves cannot take full advantage of all the extra light.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to excess of light.
exposure to high temperature.

Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
What is the source of carbon that is assimilated in photosynthesis?
