What is the habitat of t4 bacteriophage?

T4 bacteriophage primarily inhabits environments where its host, Escherichia coli (E. coli), is present, such as in the intestines of animals and in various aquatic environments. It exists in the form of free viruses in the environment, waiting to infect bacterial cells. T4 bacteriophage thrives in nutrient-rich conditions that support bacterial growth, as its lifecycle depends on the presence of E. coli to reproduce.
