What is greenhouse effect ? Discuss the effect of increased level ( between 540 and 970 ppm) of carbon dioxide gas on the growth of `C_(3)` plants .

Text Solution

Verified by Experts

As a result of the increase in greenhouse gases like CO, CFCs, `CH_(4), N_(2)O` etc., the environmental temperature increases at surface level. This process is called greenhouse effect. `CO_(2)` is the most abundant greenhouse gas in the atmosphere. Increases in the level of `CO_(2)` leads to `CO_(2)` fertilization whihc causes increase in the gorwth of `C_(3)` plants by 30%.
