A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Carbon capture is performed by the green parts of plants via photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
In some part of the stems, some photosynthesis may also occur.
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.
Almost half of the total biomass of a tree may be allocated to the roots.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
The rate of respiration decreases with temperature.
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.
Transpiration decreases as air becomes drier.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
air humidity (VPD).
soil moisture (REW).
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
