Well done!
Question:
Carbon capture is performed by the green parts of plants via photosynthesis.
Response:
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in soil temperature.
the changes in air temperature.
the changes in CO2 concentration.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
atmospheric oxygen.
soil heat.
sun light.
soil nutrients.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
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.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
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.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of CO2.
exposure to high temperature.
exposure to shortage of soil moisture.
exposure to excess of light.
