Unit 2 – Ecology Review (Chapters 3,4,5,6)
Unit 2 – Ecology Review (Chapters 3,4,5,6)
Vocabulary List: You should familiarize yourself with the glossary definition as well as the context in which these words are used in your text. (for example for ozone layer, not only the definition is important, but also explain what is happening to it and why that is important)
Study tip: Start early and give yourself an unlimited amount of quiet study time to write down and test your vocabulary knowledge. Make flash cards to quiz yourself. Quiz your friends!
