Carbon Dioxide
Early organisms turned carbon dioxide and water into oxygen through photosynthesis, making the Earth's atmosphere rich in oxygen and enabling the development of aerobic life forms. This process played a crucial role in creating suitable conditions for the evolution and diversification of organisms on Earth.
Organisms require four main things in order to continue to grow. They need food, water, sun, and oxygen in order to survive and grow.
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
Most organisms need food, water, shelter, and the ability to reproduce in order to survive. Additionally, they require a suitable environment with appropriate temperature, oxygen levels, and other specific conditions for their survival.
Unicellular organisms can obtain oxygen through simple diffusion from their environment, such as from water in the case of aquatic organisms. This process allows the oxygen to pass directly through their cell membrane and into their cytoplasm where it can be used for cellular respiration.

Earth's oxygen atmosphere was primarily created by early photosynthetic organisms, such as cyanobacteria, which converted carbon dioxide into oxygen as a byproduct of photosynthesis. Over millions of years, these organisms accumulated oxygen in the atmosphere, resulting in the oxygen-rich environment we have today.
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.

It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
Aerobic organisms use oxygen.
The five basic needs of all organisms are food, water, shelter, oxygen, and a suitable environment for growth and reproduction. Meeting these needs is essential for the survival and well-being of all living organisms.
The amount of Oxygen started to increase as more plants and animals appeared. The plants took in Carbon dioxide and gave out Oxygen. So, overtime the amount of Carbon dioxode (which was high) decreased, and oxygen increased.
The most anaerobic zone in the ocean is found in the waters near the seafloor in regions known as oxygen minimum zones (OMZs). These areas have very low levels of dissolved oxygen, making them suitable habitats for anaerobic organisms. OMZs are often located in deep ocean basins or along coastlines where oxygen supply is limited.
oxygen from the surrounding air, making it suitable for space travel where there is no atmosphere.
Earth acquired oxygen through a process called photosynthesis, where plants and certain bacteria convert carbon dioxide and water into oxygen and glucose using sunlight. Over time, these organisms produced and released oxygen into the atmosphere, leading to its accumulation. This process played a crucial role in shaping Earth's atmosphere and making it suitable for supporting complex life forms.
Organisms that release oxygen as a byproduct of photosynthesis include plants, algae, and cyanobacteria. These organisms use sunlight to convert carbon dioxide and water into oxygen and glucose, releasing oxygen into the atmosphere as a result.
