It seems like the text you provided is garbled and difficult to interpret. However, I will attempt to address what I can infer from it.

The question appears to be about how microorganisms contribute to the production or accumulation of substances essential for human life, such as oxygen (\(\mathrm{O}_2\)) and organic nitrogen compounds, in the environment.

Here's a general explanation based on this interpretation:

1. Oxygen Production:

   • Microorganisms, particularly photosynthetic ones like cyanobacteria and algae, play a crucial role in producing oxygen. Through the process of photosynthesis, these organisms convert carbon dioxide and water into glucose and oxygen, releasing oxygen into the atmosphere. This process is vital for maintaining the oxygen levels necessary for human and animal life.

2. Nitrogen Cycle:

   • Microorganisms are also essential in the nitrogen cycle, which is crucial for converting atmospheric nitrogen into forms that can be used by plants and animals. Nitrogen-fixing bacteria, such as those in the genus Rhizobium, convert atmospheric nitrogen (\(\mathrm{N}_2\)) into ammonia (\(\mathrm{NH}_3\)), which can then be used to synthesize organic nitrogen compounds. These compounds are essential for the production of amino acids, proteins, and nucleic acids in living organisms.

In summary, microorganisms are fundamental to the production and recycling of essential substances like oxygen and organic nitrogen compounds, supporting life on Earth.
