What is difference between limiting factor and range of tolerance?

A limiting factor is an environmental condition that restricts the growth, abundance, or distribution of an organism, such as availability of food, water, or light. In contrast, the range of tolerance refers to the spectrum of environmental conditions (e.g., temperature, pH) within which a species can survive and thrive. While limiting factors can prevent organisms from reaching their potential, the range of tolerance defines the boundaries of conditions that can support life for a species. Together, these concepts help explain how organisms interact with their environment and the constraints they face.
