| C.5.U1 | Sampling techniques are used to estimate population size. | |
| C.5.U2 | The exponential growth pattern occurs in an ideal, unlimited environment. | |
| C.5.U3 | Population growth slows as a population reaches the carrying capacity of the environment. | |
| C.5.U4 | The phases shown in the sigmoid curve can be explained by relative rates of natality, mortality, immigration and emigration. | |
| C.5.U5 | Limiting factors can be top down or bottom up. | |
| C.5.A1 | Evaluating the methods used to estimate the size of commercial stock of marine resources. | |
| C.5.A2 | Use of the capture-mark-release-recapture method to estimate the population size of an animal species. | |
| C.5.A3 | Discussion of the effect of natality, mortality, immigration and emigration on population size. | |
| C.5.A4 | Analysis of the effect of population size, age and reproductive status on sustainable fishing practices. | |
| C.5.A5 | Bottom-up control of algal blooms by shortage of nutrients and top-down control by herbivory. | |
