Which factor is essential for nutrient cycling contributed by bacteria?

• A. Increase in soil temperature
• B. Presence of non-pathogenic species
• C. Excessive carbon usage
• D. Decline in microbial activity

Answer: (B)

The presence of non-pathogenic species is essential for nutrient cycling contributed by bacteria because these beneficial bacteria play a critical role in breaking down organic matter and facilitating the transformation of nutrients. Non-pathogenic bacteria contribute to processes such as decomposition, nitrogen fixation, and nutrient availability for plants. By effectively metabolizing organic compounds and transforming them into more accessible forms, they help maintain the ecosystem's health and productivity. In nutrient cycling, these non-pathogenic bacteria can decompose complex organic materials, releasing nutrients like carbon, nitrogen, and phosphorus back into the soil. This not only enriches the soil but also promotes plant growth and sustains various soil microorganisms, forming a balanced ecosystem. The health of soil microbial communities, particularly those that are beneficial, directly impacts agricultural productivity and environmental sustainability.
