Energy Transfer: Owl Pellets
Objectives:
The objective of this lab is to acquire the ability to dissect owl pellets
and identify the bones found. The bones should then be used to estimate the
types of animals an owl eats in a region, and then use this information to find
the amount of energy that has been transferred to the owl, based on the
food chain.
Pre-Lab Questions:
1.Research to find out how often an owl will produce an owl pellet orhow many pellets an average owl will produce in a year.
2.Suppose you want to figure out what the following animals eat. What methods would you use? Explain how each is a valid method.
