Why is the ozone layer important for Earth's life forms? The ozone layer is important for Earth's life forms because it protects Earth from harmful ultraviolet radiation. This made the environment able to support more complex life forms. 2.) Describe the role of cyanobacteria in changing Earth's early atmosphere. Cyanobacteria helped in changing Earth's atmosphere by adding an abundance of oxygen to it. To this day cyanobacteria's account for 20% to 30% of photosynthesis today.
The ozone layer is a region in the Earthâs atmosphere that contains high concentrations of ozone. Ozone is three molecules of oxygen bonded together, and so it has the chemical symbol O 3. The ozone layer contains more than 91% of the ozone in the Earthâs atmosphere.Because it absorbs ultraviolet radiation from the Sun, the ozone layer is vital to the evolution and survival of life on Earth.zone is three molecules of oxygen bonded together, and so it has the chemical symbol O 3.
