The decrease in ozone levels allows more UV radiation to reach the Earth's surface which lead to various diseases such as skin cancer, cataracts, and weakened immune systems. The atmospheric carbondioxide gas is responsible for the increase of surface temperature by trapping reflected solar radiations so decrease in carbondioxide concentration will leads to lower surface temperature.
Answer:
its Mechanical digestion and Chemical digestion
