And when these fossil fuels are burnt in power factories, power plants, cars etc. carbon moves from the fossil to the atmosphere. And since carbon dioxide is a greenhouse gas it traps more heat and hence there is a global temperature rise.
It is estimated that every year almost five and a half billion tons of carbon is released by burning fossil fuels. And since this amount of carbon dioxide is very huge for plants to convert all of them into oxygen via photosynthesis it leads to disbalancing in the carbon cycle that is more carbon dioxide is produced than the amount can be utilized which finally leads to rise in Earth's temperature as all of the extra carbondioxide ends up in Trapping more sun light.
The chemicals help the roots of the plants to grow
