1. Big Idea 4 - Interactions
Concept 4B. Competition and Cooperation
Lesson 1: Molecular interactions
Lesson 2: Interactions within organisms
Lesson 3: Interactions between and within populations
Lesson 4: Ecosystem distribution

2. Succession
When organisms populate a new, or recently devastated ecosystem, they do so in a predictable pattern

4. In small groups, explain how
Geological and meteorological events impact ecosystem distribution
Human impact accelerates change at local and global levels

5. In small groups, explain how
Geological and meteorological events impact ecosystem distribution
El Niño
Meteor impact on the dinosaurs
Human impact accelerates change at local and global levels
This is your homework
Make sure you include the concept of competition exclusion principle

6. Be Able To
4.20 Explain how the distribution of ecosystems changes over time by identifying large-scale events
that have resulted in these changes in the past
4.21 The student is able to predict consequences of human actions on both local and global ecosystems
