INTRODUCTION TO ECOLOGY
ECOLOGY • The study of the interactions of living organisms with one another and with their environment
ORGANISM • A living thing
POPULATION • A group of organisms of the same species that live in a specific geographical location
COMMUNITY • All the populations of species that live in the same habitat and interact with each other
ECOSYSTEM • A community of organisms and their abiotic environment
BIOME • A major regional community of organisms, defined by climatic conditions and plant communities living there; they contain many ecosystems.
BIOSPHERE • The part of the Earth where life exists
EXAMPLE • Organism = Single student • Population = 7 th grade students at DMS • Community = ALL students at DMS • Ecosystem = DMS (students, staff, the classrooms, desks, etc. ) • Biome = All the middle schools in Cobb County
