Transpiration decreases as air becomes drier.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Photosynthesis of a tree canopy is driven or influenced by
air humidity (VPD).
the total leaf area (LAI).
soil moisture (REW).
air temperature (T).
photosynthetically active solar radiation (PAR).
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
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.
Almost half of the total biomass of a tree may be allocated to the roots.
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.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in air temperature.
the changes in light.
the changes in soil temperature.
Carbon capture is performed by the green parts of plants via photosynthesis.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
