Limiting factors are things that can affect an animal’s population. Limiting factors can be biotic(living) and abiotic (nonliving). Common limiting factors are food and habitat. In this lab you will look at thelimiting factors found in the Cedar Glade (Wilson County, Tennessee) ecosystem, and their impact (affect) on population growth. Objectives: Define “limiting factors.”Recognize that some fluctuations in wildlife populations are natural as ecological systems undergo constant change.Graphing the data collected to show how population size differs over time and with changes in the environment.Problem:How will the owl and mice population size be affected by limiting factors? Hypothesis:Predict how limiting factors will affect the owl and mice population size of Wilson County, Tennessee. Your hypothesis should be written in the form of an “if…, then…because” statement. If the owls and the mice interacted in an ecosystem then the owls might gain attraction for the mice and start creating a half breed of mice-owls. Materials: Bag of beans Two pipe cleaners bent in a 5 x 5 cm squares to represent the owls Masking tape Meter stick Directions: 1.Each group should have four students. Among the four students, each one should have a
