When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Plants open its stomata to avoid losing too much water.

As plants respire, they release
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Carbon capture is performed by the green parts of plants via photosynthesis.
Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.
An increment in leaf area increases also the photosynthesis of a tree stand. However, the relationship is saturating.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
In some part of the stems, some photosynthesis may also occur.
Photosynthesis of a tree canopy is driven or influenced by
air humidity (VPD).
soil moisture (REW).
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
air temperature (T).
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.
Almost half of the total biomass of a tree may be allocated to the roots.
