Stage 4: Years 7 – 12:
Multi-cellular organisms rely or coordinated and interdependent internal systems to respond to changes to their environment.
Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems.
In this program students will:
- Observe and describe some examples of how multi-cellular organisms respond to changes in their environment.
- Describe how coordinated function of internal systems in multi-cellular organisms, provide cells with the requirements for life, including gases, nutrients and water, and removes cell wastes.
- Describe how energy flows through ecosystems, including input and output through food webs.
- Analyse how changes in some biotic and abiotic components of an ecosystem affect populations and/or communities.
- Evaluate some examples in aquatic ecosystems, strategies used to balance conserving, protecting and maintaining the quality and sustainability of the environment with human activities and needs.
