Ecosystem – all the living and nonliving things in an area interacting with each other Ecology – the study of how living things and their environment interact Abiotic factor – a nonliving part of an ecosystem Biotic factor – the living part of an ecosystem Population – all the organisms of one species that live in an area at the same time Community – all the populations living in an area Habitat – the area in which an organism lives Niche – the role an organism has in its ecosystem
