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