Step 1

Step 2
1. The habitat must provide food, water, shelter, and other things the whooping crane needs to live, grow, and reproduce.
2. Answers may include destruction of habitat, pollution, and bad weather.

Step 3

Step 4
You needed to create a graph on the next page for each year of the study for the TOTAL number of Whooping Cranes (migrating adults plus the hatched eggs). Year 1 you would graph 25 (migrating adults 21 plus hatched eggs 4).
Year 2 you would graph 22 (migrating adults 20 plus hatched eggs 2) and so forth for each year of the study.

Step 5
Looking at the graph provided, notice the numbers for the years are underneath the vertical line. This would indicate that a line graph is expected.
If the number were under the column, that would indicate a bar graph should have been used.

Step 6 – Graph Answer

Step 8 – Question 7

Step 8 Continued
To compute the “Hatching Success Rate” you divide the number of eggs hatched by the number of eggs laid. Look at year 1 4 / 6 X 100 = 66.666667 or rounded to the nearest whole number is 67%.
