Answer-In water logged soils maximum microbes found are

In waterlogged soils such as rice fields, oxygen availability is very low, creating anaerobic conditions . Different microbial groups respond differently to these conditions 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 Algae Found mainly in surface water where sunlight is available, but not dominant in deeper, anaerobic soil layers. Actinomycetes Fungi Prefer aerobic oxygen-rich conditions and are much less abundant in waterlogged soils.
