Is it true that some organisms can only survive in a small range of pH levels. It the pH levels are too high or too low, the organism will die.

Is that true??

How long do you think you would survive in a vat of acid? Does that help?

Yes, it is true that some organisms can only survive within a certain range of pH levels. pH is a measure of acidity or alkalinity and ranges from 0 to 14. Organisms, including bacteria, fungi, plants, and animals, have specific pH requirements for optimal growth and survival.

If the pH levels are too high (alkaline) or too low (acidic), it can disrupt cellular processes and damage important molecules necessary for the organism's survival. For example, extreme pH levels can affect enzyme activity, protein structure, and cell membrane function.

To determine an organism's pH tolerance range, scientific experiments are conducted. Researchers expose the organism to varying pH levels and observe its response. If the organism thrives within a narrow pH range, it indicates its sensitivity to pH changes.

So, to answer your question and confirm if it is true for a specific organism, you would need to review scientific studies or research papers that investigated its pH tolerance range. The information can usually be found in reputable scientific sources such as journal articles or textbooks.
