The rate of respiration decreases with temperature.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in air temperature.
the changes in light.
the changes in soil temperature.
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.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Carbon capture is performed by the green parts of plants via photosynthesis.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
What is the source of carbon that is assimilated in photosynthesis?
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of light.
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to high temperature.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Transpiration decreases as air becomes drier.
