Almost half of the total biomass of a tree may be allocated to the roots.
What is the source of carbon that is assimilated in photosynthesis?
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of CO2.
exposure to excess of light.
exposure to shortage of soil moisture.
Photosynthesis of a tree canopy is driven or influenced by
soil moisture (REW).
air humidity (VPD).
the total leaf area (LAI).
air temperature (T).
photosynthetically active solar radiation (PAR).
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Transpiration decreases as air becomes drier.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Carbon capture is performed by the green parts of plants via photosynthesis.
In some part of the stems, some photosynthesis may also occur.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
As plants respire, they release
