The rate of respiration decreases with temperature.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Almost half of the total biomass of a tree may be allocated to the roots.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Carbon capture is performed by the green parts of plants via photosynthesis.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Photoinhibition means the decrease in photosynthesis due to

Photosynthesis of a tree canopy is driven or influenced by
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
soil moisture (REW).
air temperature (T).
air humidity (VPD).
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
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.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plants open its stomata to avoid losing too much water.
