To transform atmospheric CO2 into organic molecules, plants can use the energy from
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
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.
Photosynthesis of a tree canopy is driven or influenced by
air humidity (VPD).
air temperature (T).
the total leaf area (LAI).
soil moisture (REW).
photosynthetically active solar radiation (PAR).
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
The annual cycle of photosynthesis mainly follows
the changes in soil temperature.
the changes in CO2 concentration.
the changes in light.
the changes in air temperature.
In some part of the stems, some photosynthesis may also occur.
Transpiration decreases as air becomes drier.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
