| C.2.U3 | The percentage of ingested energy converted to biomass is dependent on the respiration rate. | |
| C.2.U4 | The type of stable ecosystem that will emerge in an area is predictable based on climate. | |
| C.2.U5 | In closed ecosystems energy but not matter is exchanged with the surroundings. | |
| C.2.U6 | Disturbance influences the structure and rate of change within ecosystems. | |
| C.2.A1 | Conversion ratio in sustainable food production practices. | |
| C.2.A2 | Consideration of one example of how humans interfere with nutrient cycling. | |
| C.2.S1 | Comparison of pyramids of energy from different ecosystems. | |
| C.2.S2 | Analysis of a climograph showing the relationship between temperature, rainfall and the type of ecosystem. | |
| C.2.S3 | Construction of Gersmehl diagrams to show the inter-relationships between nutrient stores and flows between taiga, desert and tropical rainforest. | |
| C.2.S4 | Analysis of data showing primary succession. | |
