BVHS Ecology Quiz: Trivia!

How well do you know about BVHS ecology? Ecology is the study of relationships that an organism has in its environment. For this quiz, you will want to understand what a secondary consumer is, items that may or may not be recycled, different factors in an ecosystem, and what constitutes a trophic level. This educational quiz will explain this branch of science. Good luck with this quiz.
