• I can list and define four levels of organization in the environment (organism,
population, community, ecosystem).
18.104.22.168.2 – Medium
Compare and contrast predator/prey, parasite/host and producer /consumer
• I can compare and contrast predator/prey relationships.
• I can compare and contrast parasite/host relationships.
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.
22.214.171.124.3 - 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.
126.96.36.199.1, 188.8.131.52.2, 184.108.40.206.2 – Medium (see above)
• I can compare and contrast the roles of producers, consumers, and decomposers
in an ecosystem.
220.127.116.11.3 – 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
18.104.22.168.2 - Low
Describe ways that human activities can change the populations and communities in
• I can give examples of human activities that affect ecosystems (bacterial
resistance, pollution, over-hunting, urban development, deforestation).
22.214.171.124.1 – 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.
126.96.36.199.1 – 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
