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.
Energy flow
Energy flows one-way: producers → consumers → decomposers, with heat losses.
Matter cycle
Matter is continuously recycled through biogeochemical cycles.
