BIOLOGY I

UNIT THREE:  ECOLOGY- EXPLORING THE BIOSPHERE

 

 

Introduction:

 

In this unit, students will be introduced to the relationships and interactions of living things with one another and their environment. Students will focus on gaining a general understanding of ecology, biomes and ecosystems.  The movement of energy through the biosphere will be also be investigated.

            The discussion of how populations grow and how communities grow, develop and interact is key to understanding why ecological interactions are important in peoples lives. The different mechanisms for human population growth and this effect on the environment will be discussed. For example, How is overpopulation problematic? What types of pollution do humans create and how does it effect the biosphere?

            Case studies and / or examples of ecological problems and relationships will be introduced and investigated through this unit. Students will have the opportunity to further investigate specific endangered species and to see how the ecological principles in this unit are evident in their “real” lives.

            Students will be encouraged to identify ways that the environment can be cleaned up and protected from future harm. The study of the limits of natural resources and how the stress on these resources will effect our future will be investigated.
