Answer 1

type of food), and both the number and percentage of the total food items eaten by each type of bird. Create a bar graph of percent food eaten with 36 bars (a bar for each of the six species in environment 1, env. 2, etc.) using a program like Excel. Label your graph, and color code the bars for emphasis. Include a legend which indicates the color of each species. Try this pre-built Excel table to enter and graph your data. Hope this helps you out. 

Answer 2

The percentage of food eaten is a good number to use because it compares the number of food eaten to the number of birds in the flock. If the resulting number from this multiplication is low, then the flock is unsuccessful in the collection of food - causing it to shrink. If the resulting number is high then the flock has been successful in the gathering of their food - causing the flock to grow.
