Biology II Ecology · Energy Transfer Through Ecosystems

Virginia SOL EC.3

Virginia SOL EC.3 is part of the Energy Transfer Through Ecosystems strand in Biology II Ecology (Science). Under this Standards of Learning objective, students investigate how energy is transferred through ecosystems and the role of thermodynamics. Below is what EC.3 covers in plain language, the specific skills it is assessed on, the key concepts to review, and how to practice EC.3 for the Virginia SOL test.

What SOL EC.3 means

Investigate how energy is transferred through ecosystems and the role of thermodynamics.

Skills you’ll practice for EC.3

  • Explain how the laws of thermodynamics govern energy transfers through ecosystems.
  • Explain how changes in ecosystem factors affect energy transfer and ecological efficiency in a local ecosystem.
  • Make, support, and evaluate a claim about how strategies organisms use to acquire energy lead to biodiversity within ecosystems.
  • Make, support, and evaluate a claim about how nutrient cycling by decomposers affects energy transfer in ecosystems.
