AP Biology — Ecology
Unit 8 of 8
Ecology is the eighth of 8 units in the College Board's current AP BiologyCourse & Exam Description. It builds on Natural Selection and closes out the sequence.
Our Ecology set has 12 practice questions, each with a written explanation, a one-line key takeaway, and a rationale for every wrong choice — so you learn why the right answer is right and why each distractor is tempting. You can work them as a timed set or read the worked solutions straight through.
