Investigating Owl Pellets (food webs)

Based upon the class data, rank the most frequently consumed prey for the class “owl population”.

Based on our class data the most frequently consumed prey was the rat. On the pie chart it shows that 50 % of our "Owl Population" was rat.

Try to define the food-getting “strategy” for a predator.

Every predator has its own strategy while hunting for food. If you look at owls they rely a lot on their senses. Such as keen eyesight, which seeing as they hunt at night helps them locate small things. Owls also have very sensitive hearing which helps them locate concealed prey (wouldn't you love that while playing hide and seek?) Also owls have a particular type of feathers which help conceal the sound of the air that rushes over their wing surface, all of these senses work together to help the owl in the element of surprise while hunting prey.

Based upon your data, suppose the shrew population seriously declined, would it affect the areas of the owl population?

Seeing as only 1% of or owls diet consists of eating shrews, I would say no. I think that the sudden decrease in their population might affect other animal but as for our owls diet it would not dramatically affect it. However if the should be a decline in the rat population then yes I would definitely say that it would dramatically affect our owls diet. But shrews are not the main part of the diet of the owls pellets that we dissected.

Blogger wouldn'd let me upload my pie chart. :(
