🧬 Nitrogen Cycle & Nutrient Loops
The Microbe Game
Ammonification, nitrification, denitrification — in order?
If you jumble this, nitrogen never reaches you. Match it cold.
MATCH THE COLUMN (Advanced):
1. Nitrogen Fixation → Rhizobium (symbiotic) / Azotobacter (free); N₂ → NH₃
2. Ammonification → Decomposers convert organic N → NH₄⁺
3. Nitrification → Nitrosomonas → Nitrobacter: NH₄⁺ → NO₂⁻ → NO₃⁻
4. Denitrification → Pseudomonas returns NO₃⁻ → N₂; anaerobic loss
5. Phosphorus Cycle → No atmospheric phase; sedimentary, limiting in water
Diagram: Microbial Relay — Relay baton diagram: Fixation → Ammonification → Nitrification → Assimilation → Denitrification
GIF Idea: Bacteria icons pass N-baton. Wrong match = baton drops + shake effect.
