Biological Sciences

Classification helps organise the diverse group of organisms 

Interactions between organisms can be described in terms of food chains and food webs; human activity can affect these interactions 

Cells are the basic units of living things; they have specialised structures and functions 

Multi-cellular organisms contain systems of organs carrying out specialised functions that enable them to survive and reproduce 

Multi-cellular organisms rely on 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

Transmission of heritable characteristics from one generation to the next involves DNA and genes

The theory of evolution by natural selection explains the diversity of living things and is supported by a range of scientific evidence
