⚖️ Nutrient Cycles: Three Biomes Compared
| Feature | Tropical Rainforest | Hot Desert | Temperate Deciduous Forest |
|---|---|---|---|
| Biomass store | Very large (dominant) | Very small | Large |
| Litter store | Very small (rapid decomposition) | Small (slow decomposition) | Large (seasonal leaf fall) |
| Soil store | Very small (rapid uptake) | Medium (little uptake, no leaching) | Medium to large (fertile) |
| Decomposition rate | Very fast (warm and wet) | Very slow (dry) | Moderate (seasonal) |
| Leaching rate | Very high (heavy rain) | Very low (little rain) | Moderate |
| Consequence of clearing vegetation | Rapid nutrient loss → infertile soil within years | Soil may have nutrients but lacks water for plant growth | Fertile soil persists after clearance (historically, most farmland) |
| Limiting factor for plant growth | Light (dense canopy competition) | Water | Light and temperature (seasonally) |
