1. 8. 11(C)  explore how short- and long-term environmental changes affect organisms and traits in subsequent populations

2. Environmental Changes can be natural such as _____, _____, ______, and ______ to name a few. Also, Environmental changes can be human impacts such as _____, ______, ______, and _______.

3. Long-term change effects- environmental change that occurs slowly over time and affects organisms over generations Short-term change effects- environmental change that occurs quickly and affects organism immediately

4. Biodiversity The variety of organisms in an environment or ecosystem.
Technical Definition: A structure, behavior or other trait in an organism that helps it to survive in its environment.

5. Which fox is best suited for the environment?
Natural Selection
Helpful traits are passed on to new generations.
Which fox is best suited for the environment?
Technical Definition: The process by which organisms with traits best suited to an environment survive and pass their traits to the next generation more often than organisms without these traits.
