Think about what you have learned so far about populations in general and the rough-skinned newt population that has lots of predators in the park.

What prediction would you make about the poison-level traits in this population? Explain.

Vocabulary:

1. Distribution: the number of individuals with each trait in a population

2. Histogram: a graph that uses bars to show how characteristics or values are distributed within a group

3. Population: a graph that uses bars to show how characteristics or values are distributed within a group

4. Trait: a specific characteristic of an individual organism

5. Variation: any difference in traits between individual organisms

6. Abiotic: not living organisms

7. Biotic: living organisms
