Select the option/options that increase the amount of carbon dioxide in the air.
Select the option/options that increase the amount of carbon dioxide in the air.
The correct options are
A Combustion of coal.
C Use of automobiles.
D Respiration in living organisms.
The burning of coal and other fossil fuels increases the amount of carbon dioxide and other toxic gases in the air.
Respiration is the process in which a living organism takes in oxygen and utilises it to produce energy and carbon dioxide.
Planting more trees will lead to more photosynthesis by plants in order to make their food and produce more oxygen which decreases the amount of carbon dioxide in the air.
Automobiles use petrol and diesel which undergo combustion in order to produce energy which is used to run the vehicle. The combustion of these fuels produces carbon dioxide and other toxic gases as well.
So among the given options planting more trees is the only option that decreases the amount of carbon dioxide in air rest all the other options increase the amount of carbon dioxide in the air.
