The rate of respiration decreases with temperature.
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.
Transpiration decreases as air becomes drier.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of light.
exposure to excess of CO2.
exposure to shortage of soil moisture.
As plants respire, they release
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Carbon capture is performed by the green parts of plants via photosynthesis.
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.
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.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
What is the source of carbon that is assimilated in photosynthesis?
