In water logged soils maximum microbes found

Solution

In waterlogged soils (such as rice fields), oxygen availability is very low, creating anaerobic conditions . Different microbial groups respond differently to these conditions:

1. Bacteria – Most dominant because many species are facultative anaerobes (can live with or without oxygen) or obligate anaerobes (thrive only in oxygen-free environments). Examples include:
   • Fermentative bacteria (break down organic matter)
   • Sulfate-reducing bacteria (e.g., Desulfovibrio)
   • Methanogens (produce methane in waterlogged soils)
2. Algae – Found mainly in surface water where sunlight is available, but not dominant in deeper, anaerobic soil layers.
3. Actinomycetes & Fungi – Prefer aerobic (oxygen-rich) conditions and are much less abundant in waterlogged soils.
