A complex microbiota lives belowground, releasing carbon dioxide to the soil.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
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.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
air humidity (VPD).
photosynthetically active solar radiation (PAR).
air temperature (T).
soil moisture (REW).
The rate of respiration decreases with temperature.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to high temperature.
exposure to excess of light.
exposure to excess of CO2.
In some part of the stems, some photosynthesis may also occur.
The annual cycle of photosynthesis mainly follows
the changes in air temperature.
the changes in light.
the changes in CO2 concentration.
the changes in soil temperature.
Almost half of the total biomass of a tree may be allocated to the roots.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
