Final answer:
Most microbes live and grow in habitats between pH 7 and 9. Bacteria are generally neutrophiles and grow best at a pH close to 7. Acidophiles grow optimally at a pH near 3, while alkaliphiles grow best between a pH of 8 and 10.5. Microorganisms grow best at their optimum growth pH.
Step-by-step explanation:
The majority of microbes live and grow in habitats between pH 7 and 9.
Bacteria are generally neutrophiles and grow best at a pH close to 7.
Acidophiles grow optimally at a pH near 3, while alkaliphiles grow best between a pH of 8 and 10.5.
Microorganisms grow best at their optimum growth pH, and growth occurs slowly or not at all below the minimum growth pH and above the maximum growth pH.
