Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
As plants respire, they release
Almost half of the total biomass of a tree may be allocated to the roots.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Photosynthesis of a tree canopy is driven or influenced by
soil moisture (REW).
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
air temperature (T).
air humidity (VPD).
Carbon capture is performed by the green parts of plants via photosynthesis.
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.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
In some part of the stems, some photosynthesis may also occur.
The rate of respiration decreases with temperature.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
The annual cycle of photosynthesis mainly follows
the changes in soil temperature.
the changes in light.
the changes in air temperature.
the changes in CO2 concentration.
