As a specialized discipline within the field of Biology, Ecology studies the connections, impact and interaction between organisms. Characteristics such as Energy Pyramids, Producers and Consumers and Symbiotic Relationships comprise the backbone of this area of study. Learn to differentiate between organisms in Autotrophs vs. Heterotrophs and master the concept of how life forms and the environment interact and impact each other in Ecosystem. Explore the key elements required to identify placement in Energy Pyramids and establish hierarchy of consumption in Food Webs and Producers and Consumers. From the most granular concepts to the big picture, Ecology provides skills and insights to the environment and life forms within it.
