The rate of respiration decreases with temperature.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
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.
Carbon capture is performed by the green parts of plants via photosynthesis.
Photoinhibition means the decrease in photosynthesis due to

The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in CO2 concentration.
the changes in air temperature.
the changes in soil temperature.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
As plants respire, they release
In some part of the stems, some photosynthesis may also occur.
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.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
