Verified step by step guidance

Understand that microorganisms play diverse roles in various ecosystems and human activities.

Recognize that microorganisms are involved in food and drink production, such as in the fermentation process used to make bread, beer, and yogurt.

Acknowledge that certain microorganisms, like cyanobacteria, contribute to the removal of carbon dioxide from the atmosphere through photosynthesis.

Identify that some microorganisms, such as nitrogen-fixing bacteria, convert atmospheric nitrogen into forms that plants can use for growth, thus supporting agriculture.

Realize that microorganisms are integral to sewage treatment processes, where they help break down organic matter, reducing pollution and treating wastewater.

Note that bioremediation involves using microorganisms to remove pollutants from the environment, such as oil spills or heavy metals, highlighting their role in environmental cleanup.
