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

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

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

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

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
