What is an ecological system called that consists of all of its biotic and abiotic factors?
a-community
b ecosystem
c habitat
d pure culture

B. Ecosystem. By definition, an ecosystem is composed of both its abiotic and biotic factors. A community is the population of living organisms in an ecosystem, and a habitat is the generally abiotic location in which the community lives, so "ecosystem" can also be thought of as the inclusion of a community and habitat together. "Pure culture" would more closely describe a population that you might grow on a Petri dish, for instance.
