• The major structural and functional dynamics of your selected ecosystem

• How humans may have affected the cycling of matter in ecosystems, including effects to the nitrogen, phosphorus, or carbon cycle

• How knowledge about that ecosystem's structure and function can help or has helped to develop plans for its restoration or management

• The implication of species interactions on your selected ecosystem
