The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in CO2 concentration.
the changes in soil temperature.
the changes in air temperature.
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.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Almost half of the total biomass of a tree may be allocated to the roots.
In some part of the stems, some photosynthesis may also occur.
As plants respire, they release
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
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.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
soil moisture (REW).
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
air humidity (VPD).
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
