In fact, there are bacteria that grow in all kinds of pH, from the most acidic to the bad alkaline. Depending on the pH at which they live, bacteria can be classified as neutrophil, acidophilic and alkalineophilic.
But in general, when we talk about bacteria that are present in foods, they tend to grow in a pH range between 5 and 9, so they are considered as <u>neutrophil</u>. This can vary by species and other factors such as temperature and available nutrients.
Ecological succession provides diversity and depth to a biotic community. Without it, life can not grow or progress. ... ( I don’t know if this will help you but here you go. )
