The process in which oxygen is released into atmosphere is:
Green house
Photosynthesis
Combustion
Carbon cycle
The main source of atmospheric free oxygen is photosynthesis, which produces sugars and free oxygen from carbon dioxide and water.
During the process of photosynthesis, carbon dioxide is released into the atmosphere and oxygen present in the atmosphere is used by the plants.
The cycle in nature in which oxygen is consumed for the burning of fuels as well as for respiration and is released by the process of photosynthesis is called
Green house gases (carbon dioxide, methane, etc) are useful for atmosphere as it traps heat in the atmosphere so that there is a proper balance of temperature. But excessive amount of greenhouse gases cause several problems. Which among the following is caused due to the excessive release of green house gases in the atmosphere?
