What is the role of plants in controlling air pollution?
Answer:
There is a balance between the C02 which occurs at the Earth’s surface, C02 dissolved in oceans, and that found in marine and terrestrial sediments. The burning of fossil fuels increases the amount of C02 in the atmosphere causing air pollution. Plants control air pollution because during the process of photosynthesis, they take in C02 from the atmosphere and in turn release 02. Thus, decreasing the level of C02 in the atmosphere.
