Have students choose a particular plant and/or animal that naturally inhabits your region and describe how it is adapted to the particular climate (abiotic factors) of your region (and perhaps microclimate of where it grows).
Discuss how the natural ecosystem (biome) of your region fits the definition of being an assemblage of plants, animals, and microbes interacting with each other and the abiotic environment in such a way as to sustain the assemblage over indefinite time. Make diagrams showing how it recycles nutrients and every species runs directly or indirectly on solar energy.
Since every species within an ecosystem is adapted to the particular abiotic factors of that region, observe and discuss how changing a single factor, e.g., temperature, can disrupt the entire ecosystem.
