Environmental Science and Level II Expanded · Ecosystems and Dynamic Equilibrium

Virginia SOL ENV.4

Virginia SOL ENV.4 is part of the Ecosystems and Dynamic Equilibrium strand in Environmental Science and Level II Expanded (Science). Under this Standards of Learning objective, students investigate and understand ecosystems in a state of dynamic equilibrium affected by biotic and abiotic interactions. Below is what ENV.4 covers in plain language, the specific skills it is assessed on, the key concepts to review, and how to practice ENV.4 for the Virginia SOL test.

What SOL ENV.4 means

Investigate and understand ecosystems in a state of dynamic equilibrium affected by biotic and abiotic interactions.

Skills you’ll practice for ENV.4

  • Compare biotic and abiotic factors in terrestrial and aquatic ecosystems.
  • Describe the ecological role that an organism plays in supporting the overall sustainability of the ecosystem.
  • Make, support, and evaluate a claim about the ecological roles of different categories of species in maintaining or disrupting ecosystem equilibrium.
  • Predict the effect caused by the introduction of an invasive species on the equilibrium of an ecosystem.
  • Develop and use models to predict the effects of energy and matter transfer in ecosystems.
  • Make, support, and evaluate a claim about how energy and matter are conserved in ecosystems.
  • Make, support, and evaluate a claim about how environmental pressures may lead to shifts in ecosystem equilibrium.
  • Explain how ecosystems change over time through succession and how this affects ecosystem dynamics.
  • Predict the effect of natural processes and human activities on Virginia's biodiversity and ecosystem equilibrium.
