By the end of this unit students will understand that life depends on energy flow through systems. They will recognize the many energy transformations that take place, and focus especially on the transformation of radiant energy to chemical energy in the process of photosynthesis. Students will also understand that as energy is transferred throughout an ecosystem and is used or transformed along the way. They will be able to diagram the flow of energy in a number of manners including: food chains, food webs, and energy pyramids. Lastly, students will leave this unit understanding that organisms and their environments; both living and non-living are interconnected. They will be able to describe various environments and the biodiversity created in those ecosystems. In addition they will be able to describe how an environment and the organisms in it attempt to maintain balance when disrupted. In the end students will be able to take a plot of land and describe the different ecological features of it from biodiversity to energy flow and predict its response to various internal and external factors.
