Chapter 1: The Biosphere of Life


Figure 1: Peregrine Falcon: Pixabay	In this chapter you will study factors that affect the survival of a species. These factors relate to both non-living and living components. The context for most of this chapter has an Alberta flavour. For example, the peregrine falcon is used to show the unexpected consequences of pesticide use on prairie wildlife. Near the end of Chapter 1 the view begins to widen to prepare you for Chapter 2, which has a more global context.
