Ecosystems quiz with 10 multiple choice questions. I use these with a scanable bubble sheet for easy marking.
This is version 1. I also have a version 2 in case you have a couple classes of the same. I've used this in Science 10 as a quick check to see that the students are keeping up with their studies.
It touches on trophic levels, producers and consumers, food web, Laws of thermodynamics, Pyramid of energy, ecological niche,
