Matter Flow Through Ecosystems

Virginia SOL EC.4

Investigate how matter flows through ecosystems via biogeochemical cycles.

What students need to be able to do

  • Develop and use a model to explain the cycling of matter in ecosystems through biogeochemical cycles (carbon, nitrogen, water, and phosphorus).
  • Develop and use a model to explain how the movement of one nutrient affects an ecosystem.
  • Analyze and interpret data to predict how changes in the availability of resources will affect species' success in ecosystems.
  • Make, support, and evaluate a claim about how a disruption in a biogeochemical cycle affects an ecosystem.
  • Make, support, and evaluate a claim about how changes in resource availability affect the biodiversity of an ecosystem.
