Answer:
Carbondioxide gas is a greenhouse gas which is released in the atmosphere by industries and respiration process. This carbondioxide gas is absorbed by the plant from the atmosphere in the process of photosynthesis. Some carbondioxide is also dissolved in the sea water. When the concentration of carbondioxide is increased in the atmosphere, increase in the temperature occurs due absorption of infrared radiation coming from the earth after reflection. This increase in temperature is called global warming.
