To draw suitable graphs for each sea creature, students will first need to decide on the vertical scale. This is determined by the greatest depth one of the creatures is found at. The graphs for each customer are shown in the answers.
To find the solution to question 3, students may draw a graph for all the sea creatures or scan the table for depth ranges that include 22 metres. This means that the creatures that are likely to be seen at that depth will be whales, John Dory fish, and sea horses.
