Concept:Soil organisms are affected by pH, organic matter, temperature, and physical soil conditions; good soil structure supports microbes.
Explanation:Soil pH influences the survival and population of soil organisms.
Organic matter provides food for soil organisms, so their population increases as organic matter increases.
Soil temperature affects the growth, activity, and metabolism of soil organisms.
Good soil texture and structure improve aeration, water retention, and nutrient availability, making the soil a suitable habitat for microbes.
Thus, the statement claiming that good texture and structure cannot harbour soil microbes is incorrect.
Answer:C. soil with good texture and structure cannot harbour soil microbes
