Biology II Ecology · Matter Flow Through Ecosystems

Virginia SOL EC.4

Virginia SOL EC.4 is part of the Matter Flow Through Ecosystems strand in Biology II Ecology (Science). Under this Standards of Learning objective, students investigate how matter flows through ecosystems via biogeochemical cycles. Below is what EC.4 covers in plain language, the specific skills it is assessed on, the key concepts to review, and how to practice EC.4 for the Virginia SOL test.

What SOL EC.4 means

Investigate how matter flows through ecosystems via biogeochemical cycles.

Skills you’ll practice for EC.4

  • 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.
