What might happen to the populations of
walkingsticks and birds in the bush environment over
time?

Limiting FactorsLimiting Factors•Besides predation by birds, what other factors might limit the walkingstick population?
•Are these factors biotic or abiotic?

How would you describe these organisms?
![Page 11: Investigation 8 2b](https://reader035.vdocuments.net/reader035/viewer/2022062513/5563ba1cd8b42a38198b519f/html5/thumbnails/11.jpg)
FEATURE• Any general
structure, characteristic, or behavior of an organism– Wings, fur, pattern,
color and migration– ALL have this
![Page 12: Investigation 8 2b](https://reader035.vdocuments.net/reader035/viewer/2022062513/5563ba1cd8b42a38198b519f/html5/thumbnails/12.jpg)
TRAIT• The specific
expression of a feature in an individual– Wing length, number
of spots, thickness of fur, intensity of color, timing of migration
– SOME have this

VARIATION• When there are several traits for the
same feature in a population– One example are the 3 different colors
exhibited by walking sticks
• Allows a population to survive even if the environment changes
