Analogy
Cycles and biodiversity 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.

Carbon cycles through photosynthesis, feeding, respiration and decomposition.
The water cycle moves water by evaporation, condensation and precipitation.
Biodiversity helps ecosystems stay stable.
