Microbial ecology is the study of the interactions between microorganisms and their environment, including relationships with other organisms and the impact of these interactions on ecosystem function. This field examines microbial communities in various habitats, such as soil, water, and the human body, focusing on their roles in nutrient cycling, disease, and ecosystem health. Understanding microbial ecology is essential for addressing issues like bioremediation, agriculture, and public health, as microorganisms play critical roles in maintaining ecological balance and influencing various biological processes.
