Bio Graphs

Age 14 to 16 Challenge Level:


These four graphs can be used to represent growth rates of certain organisms. How many possibilities can you suggest for each one?


Can you suggest organisms which grow according to a qualitatively different type of graph?

The graphs are all without scale on the axes.

For any possibility you suggested for the graphs, what would be a sensible scale for the axes in each case to make the graphs make sense?
