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 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.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in air temperature.
the changes in CO2 concentration.
the changes in soil temperature.
As plants respire, they release
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Carbon capture is performed by the green parts of plants via photosynthesis.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
The rate of respiration decreases with temperature.
Plants open its stomata to avoid losing too much water.
