What Microbes Thrive in Waterlogged Soil

Question

What microbes thrive in waterlogged soil?
A) anaerobes
B) obligate aerobes
C) halophiles
D) thermophiles
E) bacteria capable of forming endospores

Accepted Answer

Anaerobes are microbes that can survive and grow in environments where oxygen is absent or in low concentrations. In waterlogged soil, the soil pores become filled with water, creating an oxygen-free environment. Therefore, anaerobes are the microbes that thrive in waterlogged soil.

Answer: E 
 Endospore-forming bacteria are microbes that can form dormant structures called endospores, which can survive in harsh environmental conditions, such as high temperatures, desiccation, and exposure to chemicals. In waterlogged soil, the nutrients and oxygen level can be limiting, and the presence of toxic compounds can be high. Therefore, bacteria capable of forming endospores can thrive in waterlogged soil by forming endospores that can protect them from the harsh environmental conditions.
