I can compare and contrast the roles of producers, consumers, and decomposers in an ecosystem.
I can identify that producers carry out photosynthesis.

I can trace the flow of matter in an ecosystem.
I can give examples of human activities that affect ecosystems (bacterial resistance, pollution, over-hunting, urban development, deforestation).
I can describe patterns and make predictions about ecosystems using maps, satellite images and/or other data sets.
I can state that photosynthesis requires energy from the sun, water and carbon dioxide to produce sugar and oxygen.I can describe how the sugars produced by photosynthesis are used in cellular respiration.
