Chapter 50 An Introduction to Ecology and the Biosphere Lecture Outline Overview: The Scope of Ecology Ecology  is the scientific study of the interactions between organisms and their  environment. Concept 50.1 Ecology is the study of interactions between organisms and the environment Ecologists ask questions about factors affecting the distribution and abundance of  organisms. Ecologists might study how interactions between organisms and the environment affect the  number of species living in an area, the cycling of nutrients, or the growth of populations. Ecology and evolutionary biology are closely related sciences. Ecology has a long history as a descriptive science. Modern ecology is also a rigorous experimental science. Ecology and evolutionary biology are closely related sciences. Events that occur over ecological time (minutes to years) translate into effects over  evolutionary time (decades to millennia). For example, hawks feeding on field mice kill certain individuals (over ecological time),  reducing population size (an ecological effect), altering the gene pool (an evolutionary
