Week Six:
Energy transformations - the distinction between photosynthetic autotrophs, chemosynthetic autotrophs and heterotrophs - aerobic and anaerobic cellular respiration as a chemical process that commonly uses glucose to produce energy for the cell in both autotrophs and heterotrophs (ATP) - photosynthesis as a chemical process in which solar energy is captured and transformed to chemical energy by fixing carbon to produce a carbohydrate and releasing oxygen as a by-product

Functioning systems - a study of one selected vascular plant with reference to how its cells are specialised and organised (cells into tissues, and tissues into organs) for the intake, movement and loss of water from the plant - a study of one selected mammalian system (circulatory, digestive, excretory or respiratory) with reference to how cells in the system are specialised and organised (cells into tissues and tissues into organs), how a specific malfunction can lead to biological consequences and how the system is interconnect to other systems for the survival of the organism |

AOS 2: How do living systems sustain life?
Week Eleven:
Survival through adaptations and regulation - successful adaptations as models for biomimicry to solve human challenges - how regulation of factors is needed to maintain a relatively constant internal environment, explained by the stimulus-response model and the use of homeostatic mechanisms including feedback loops - factors regulated by homeostatic mechanisms in humans, including temperature, blood glucose and water balance - malfunctions in homeostatic mechanisms that result in diseases, including Type 1 diabetes and hyperthyroidism in humans. |
Week Twelve:
Survival through adaptations and regulation - how regulation of factors is needed to maintain a relatively constant internal environment, explained by the stimulus-response model and the use of homeostatic mechanisms including feedback loops - factors regulated by homeostatic mechanisms in humans, including temperature, blood glucose and water balance - malfunctions in homeostatic mechanisms that result in diseases, including Type 1 diabetes and hyperthyroidism in humans. |
Week Thirteen:
Survival through adaptations and regulation - successful adaptations as models for biomimicry to solve human challenges - the structural, physiological and behavioural adaptations that enhance an organism’s survival and enable life to exist in a wide range of environments Organising biodiversity - classification of biodiversity, past and present, into taxonomic groups based on shared morphological and molecular characteristics, and naming using binomial nomenclature |
Week Fifteen:
Relationships between organisms within an ecosystem - the beneficial, harmful and benign relationships between species including amensalism, commensalism, mutualism, parasitism and predation - interdependencies between species as represented by food webs, including impact of changes to keystone species. |
Week Fourteen:
Organising biodiversity - strategies for managing Earth’s biodiversity to support the conservation of species and as a reservoir for the bio-prospecting of new food sources and medicinal drugs. |
Week Sixteen:
Relationships between organisms within an ecosystem - the distribution, density and size of a population of a particular species within an ecosystem and the impacts of factors including available resources, predation, competition, disease, chance environmental events, births, deaths and migration. |
