Biomes What Is Ecology? • Ecology is the science that deals with all kinds of biological interactions. • Individuals of all species interact in various ways with individuals of their own and other species, and with their physical environment. • These interactions influence the structure of communities, ecosystems, and the biosphere. • The term “environment,” as used by ecologists, includes both abiotic (physical and chemical) factors and biotic factors (all other organisms living in an area). • Information and insights from ecological science are needed to solve many practical problems. • An understanding of ecology helps us to solve a variety of problems, including how to grow food, control pests and diseases, and deal with natural disasters. 1. Ecological systems can be as small as individual organisms or as large as the entire biosphere. 2. Ecologists study nature from several different perspectives 3. Plants, animals and microorganisms play different roles in ecological systems 4. The habitat defines an organism’s place in nature; the niche defines its functional role 5. All ecological systems and processes have characteristic scales in time and space
