Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Transpiration decreases as air becomes drier.
The rate of respiration decreases with temperature.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
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.
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.
In some part of the stems, some photosynthesis may also occur.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
photosynthetically active solar radiation (PAR).
air humidity (VPD).
soil moisture (REW).
the total leaf area (LAI).
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
To transform atmospheric CO2 into organic molecules, plants can use the energy from
