Microbial Life in Aquatic Environments

The different types of water habitats for microorganisms mentioned in the text are atmospheric water (rain, snow), surface water (rivers, streams, oceans, lakes), underground water (deep wells, springs), and stored water (stagnating water, ponds).

The ecological factors that influence aquatic microorganisms include dissolved gases (low oxygen diffusion, temperature, light, pH, nutrient concentrations, and depth and areal distribution.

Aquatic microorganisms have small size, ultramicrobacteria cells with a large surface area to intracellular volume ratio, and the ability to survive in oligotrophic conditions.
