Answer:
Through transpiration and use of carbon dioxide (green house gas)
Explanation:
Plants help in making the climate stable in following two ways –
a) Temperature offsetting – Plants take in carbon dioxide from atmosphere and thereby reduces atmospheric carbon. Due to reduction in greenhouse gases, the temperature reduces.
b) Moisture regulation – Plants transpire through their leaves. Through transpiration, they release water as vapor and cool down the air. The higher the vegetation , the more is the transpiration.
