Which factors influence the survival of bacteria in the soil?

• A. Sunlight and rainfall
• B. Moisture, temperature, pH, and organic matter
• C. Soil compaction and density
• D. Soil moisture and biomass

Answer: (B)

The survival of bacteria in the soil is mainly influenced by moisture, temperature, pH, and organic matter. Moisture is crucial as it affects the availability of nutrients and supports microbial metabolic activities. Without adequate water, bacteria can become inactive or die. Temperature also plays a key role; most bacteria thrive within a specific temperature range, and extreme temperatures can inhibit their growth or lead to their death. The pH of the soil affects bacterial survivability since bacteria have optimal pH ranges for their activities. Dramatic deviations from this range can lead to reduced growth or even death. Organic matter provides essential nutrients and energy sources for bacteria, influencing their growth and reproduction. This combination of factors creates a suitable habitat for bacteria, allowing them to perform vital functions in soil health and ecosystem balance.
