Cite evidence that living systems follow the law of conservation of mass and energy.
Describe and investigate the process of photosynthesis, such as the roles of light, carbon dioxide, water and chlorophyll; production of food, release of oxygen. Describe and investigate how cellular respiration breaks down food to provide energy and release carbon dioxide. Construct a scientific model of the carbon cycle to show how matter and energy are continuously transferred within and between organisms and their physical environment. |
