• • I can list and define four levels of organization in the environment (organism,
    population, community, ecosystem). 
    7.4.2.1.2 – Medium
    Compare and contrast predator/prey, parasite/host and producer /consumer
    decomposer relationships.
    • I can compare and contrast predator/prey relationships. 
    • I can compare and contrast parasite/host relationships. 
    7.4.2.2.2 –Medium
    Describe the roles and relationships among producers, consumers and decomposers in
    changing energy from one form to another in a food web within an ecosystem.
    • I can construct a food web and understand how energy is transferred between 
    levels in the energy pyramid. 
    7.4.2.2.3 - Medium
    Explain that the total amount of matter in an ecosystem remains the same as it is
    transferred between organisms and their physical environment, even though its
    form and location change. 
    • I can trace the flow of matter in an ecosystem.
    7.4.2.1.1, 7.4.2.1.2, 7.4.2.2.2 – Medium (see above)
    • I can compare and contrast the roles of producers, consumers, and decomposers 
    in an ecosystem. 
    7.4.2.1.3 – Medium
    Explain how the number of populations an ecosystem can support depends on the 
    biotic resources available as well as abiotic factors such as amount of light and water,
    temperature range and soil composition.
    • I can define and give examples of living (biotic) and non-living (abiotic) things 
    within an ecosystem. 
    • I can explain how changes in biotic and abiotic factors can affect populations in 
    an ecosystem. 
    7.4.4.1.2 - Low
    Describe ways that human activities can change the populations and communities in
    an ecosystem.
    • I can give examples of human activities that affect ecosystems (bacterial
    resistance, pollution, over-hunting, urban development, deforestation). 
    7.1.3.4.1 – High
    Use maps, satellite images and other data sets to describe patterns and make 
    predictions about natural systems in a life science context. For example: Use online
    data sets to compare wildlife populations or water quality in regions of Minnesota.
    • I can describe patterns and make predictions about ecosystems using maps, 
    satellite images and/or other data sets. 
    7.4.2.2.1 – Medium
    Recognize that producers use the energy from sunlight to make sugars from carbon
    dioxide and water through a process called photosynthesis. This food can be used 
    immediately, stored for later use, or used by other organisms.
    • I can identify that producers carry out photosynthesis. 
    • 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.
