Owl Prey graph and pie chart

Answers to questions 1,3,5 in packet.
My data collected:
5.50%- Birds
1.11%- Shrew
20.32%-Mouse
31.44%- Vole
41.61%- Rat
1. Looking at the data we collected as a class I think that the prey that is most frequently consumed by the "owl population" is the Rat. This makes sense because rats are big which means nutrients and more food for the owl. Yet also rats are fast breeders and their are lots of them. Also rats are usually slower and less quick making them easy prey.
3. I think the smarter choice between 35 insects at 1g each or one 35g vole when looking at conserving energy is definitely the vole, because both of them will give you the same energy value if you didn't have to hunt for them. Since you have to find each insect, which would mean you would have to hunt, eat, hunt, eat, etc., you are wasting the energy you just collected on hunting again yet with the vole you simply catch, eat, rest which means in conclusion you will have much more energy.
5. Looking at the data we collected you will see that the percentage of shrew in an owls diet is 1%, which is not very much at all. So if the shrew population declined I doubt it would have any to no affect whatsoever. This is because shrews are such a small part of the owl diet they really do not depend on them.
