Read the observation or data setting first.
Identify whether the question is about populations, communities, energy flow, material cycles, ecosystems, or human impacts.
Pay attention to arrows, relationships, and time scale.
In ecology, arrows may show energy flow, matter movement, or cause-and-effect. Check what each arrow means.
