Virginia SOL ENV.4
Virginia SOL ENV.4 is part of the Ecosystems and Dynamic Equilibrium strand in Environmental Science (Science). Under this Standards of Learning objective, students investigate and understand ecosystems in 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 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 an organism plays in supporting ecosystem sustainability.
- Make, support, and evaluate claims about ecological roles of different species in maintaining or disrupting ecosystem equilibrium.
