Best Answer: Yes, there is an optimum temperature range for organisms to grow at. Generally this range is anywhere from 15C (59F) to 45C (about 133F).Some organisms called extremeophiles can survive in extreme cold or hot as well. For the cold virus the optimum temperature is body temperature which is around 37C. The virus can survive in water droplets in the environment for up to 3-4 hours.est Answer: Yes, there is an optimum temperature range for organisms to grow at.
