How do microorganisms produce energy to stay alive?

Answer 1

This depends on what microorganism. Some microorganisms, like microscopic plants and some bacteria, are autotrophic (specifically phototrophic), meaning they create their own energy using (mainly) water and sunlight. Other microorganisms, like some bacteria and fungi, are heterotrophic, meaining they consume other organisms to get their energy.

Answer 2

Microorganisms produce energy through various processes such as respiration, fermentation, and photosynthesis. These processes involve breaking down organic molecules to generate ATP, the energy currency of cells. The specific method used depends on the organism and its environment.
