Which of the following effects did the emergence of organic molecules have on Earth's early atmosphere and organisms?
A
Increased nitrogen levels resulting in the formation of the ozone layer
B
Decreased carbon dioxide levels causing a cooling effect
C
Decreased methane levels leading to the extinction of anaerobic organisms
D
Increased oxygen levels leading to the development of aerobic organisms
Verified step by step guidance1
Understand the context: The emergence of organic molecules is linked to the process of photosynthesis, which is carried out by early photosynthetic organisms.
Recognize the role of photosynthesis: Photosynthesis is a process that converts carbon dioxide and water into glucose and oxygen, using sunlight as energy. This process is crucial for increasing oxygen levels in the atmosphere.
Connect photosynthesis to atmospheric changes: As photosynthetic organisms proliferated, they released oxygen as a byproduct, gradually increasing the oxygen concentration in Earth's atmosphere.
Consider the impact on organisms: The rise in oxygen levels allowed for the evolution and development of aerobic organisms, which use oxygen for respiration, leading to more efficient energy production compared to anaerobic processes.
Conclude the effect: The increase in atmospheric oxygen due to the emergence of organic molecules and photosynthesis was a pivotal factor in the development of aerobic life forms on Earth.
