Chapter 1: Introduction: Ecology, Evolution, and the Scientific Method Ecological systems exist in a hierarchical organization. The most powerful research projects are ones that bring together field observations, experiments and modeling. The ecological approach to human factors that emerged is the application of ecological psychology to engineered systems rather than to natural habitats (Flach et al., 1995; Hancock et al., 1995). Primary producers. The study of environments generally begins with field observations. Field data is a great first step to understanding an ecosystem, but there are always questions that can’t be answered with the field surveys.
