Years 7 to 10 Biology

Levels 7 & 8
 

There are differences within and between groups of organisms; classification helps organise this diversity.

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

Interactions between organisms can be described in terms of food chains and food webs and can be affected by human activity.

Multicellular organisms contain systems of organs that carry out specialised functions that enable them to survive and reproduce.

Levels 9 & 10

Multicellular organisms rely on coordinated and interdependent internal systems to respond to changes to their environment.

An animal’s response to a stimulus is coordinated by its central nervous system (brain and spinal cord); neurons transmit electrical impulses and are connected by synapses.

The 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.

Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems.
