Multiple Choice

A collection of all the organisms that live in a particular place, together with their nonliving environment is called what?

Think of an ecosystem as a complete system where living organisms and the nonliving environment around them form one integrated unit. This includes plants, animals, microbes together with air, water, minerals, climate, and other physical factors, all interacting and supporting energy flow and nutrient cycles. That combination—living things plus their physical surroundings—best fits the description given. A habitat refers to the specific place and its conditions where an organism or population lives, focusing on location rather than the full system. A community means all the living organisms in an area, without the nonliving environment. A biosphere spans all ecosystems on Earth, encompassing every living thing and their environments globally.
