The key to success in teaching a unit on ecology is to provide good instruction followed by a good review exercise.
This PowerPoint consists of 50 slides of questions and answers and provides an excellent review for the chapter test. I use this review PowerPoint after completing the material in this unit: Community Ecology PowerPoint and Notes.
This is NOT a teaching PowerPoint. It is strictly for review purposes. Each slide has one question followed by one answer.
PLEASE NOTE: This PowerPoint is also included in my Community Ecology Complete Lesson Plan Bundle
The questions are of varying difficulty levels. Many of the questions are basic and concrete in nature, but many of the questions involve critical thinking and problem solving skills.
This set of questions is perfect for any type of game format. Students can form groups and compete with one another during the review exercise. The review PowerPoint can also be used in a computer lab with each student reviewing independently and silently.
This review PowerPoint is appropriate for any biology or life science class with students in grades 7 - 12.
Topics covered by this review are:
1. Community Interactions: Definition of community, types of community interactions such as competition, predation, symbiosis, mutualism, commensalism, and parasitism.
