Analogy
Ecosystems is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
An ecosystem includes a community of organisms and the physical environment.
Biotic factors are living factors; abiotic factors are non-living factors.
Changes in one population can affect other populations in a food web.
