Final answer:
Microorganisms have an ideal temperature range for growth. Mesophiles, which include many pathogens, prefer temperatures between 20°C and 45°C. Psychrophiles prefer cold temperatures, while thermophiles thrive in hot temperatures.
Step-by-step explanation:
Microorganisms have an ideal temperature range for growth. This range can vary depending on the type of microorganism, but generally, mesophiles (including most pathogens) grow best at temperatures between 20°C and 45°C. Psychrophiles prefer cold temperatures between 0°C and 15°C, while thermophiles thrive in temperatures between 50°C and 80°C.
