## 'Bio Graphs' printed from http://nrich.maths.org/

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?
