1. Use the graph paper
below to plot these results. Remember to label your axes. The vertical
axis represents the lung volume /dm3and the horizontal axis
represents the body mass /kg.
 |
| 2. What do you observe when you
compare these animals of different sizes and their lung volumes? |
|
| 3. The badger has a body mass of
about 12kg. What would you expect its lung volume to be? |
