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.
Quick Answer. Earthâs atmosphere protects life on the surface by filtering deadly ultraviolet radiation, destroying most meteors that pass through it and retaining heat. The atmosphere also provides oxygen to humans and carbon dioxide to plants. The atmosphere consists of five layers and is approximately 60 miles thick. The layer closest to the surface is called the troposphere, and it provides the majority of the planetâs oxygen. This layer is also responsible for weather, including rain, which protects Earth's inhabitants from drought and starvation.
