Multi-cellular organisms rely or coordinated and interdependent internal systems to respond to changes to their environment.
Ecosystems consist of communities of indertependent organisms and abiotic components of the environment; matter and energy flow through these systems
Observe and describe some examples of how multicellular organisms respond to changes in their environment.
Describe how coordinated function of internal systems in multicellular organisms provides 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 ecosystems, of strategies used to balance conserving, protecting and maintaining the quality and sustainability of the environment with human activities and needs.
