Observe → describe → explain
Start from facts (document/experiment), then build a reasoned scientific explanation.
Precise scientific vocabulary
Use exact terms: ecological factor, valence, productivity, biotope, biocenosis, reproduction.
Limiting factor
Growth/activity depends on the most constraining environmental factor.
Ecological valence
Wide valence = euryecious species; narrow valence = stenoecious species.
