After your introductory unit on ecology, you'll want to follow it up with a unit on community ecology. These 56 slides will captivate your students with stunning photographs and images to provide an in-depth study of community ecology principles. Choose to use the traditional printable version, or the paperless, digital Google Apps version. The PowerPoint covers all the topics you would expect from this chapter of a traditional high school biology textbook, including the six types of community interactions, properties of communities, and succession. A detailed list of the topics covered can be found below.

This resource is perfect for traditional classroom settings, distance learning, flipped classrooms, or for students in 1:1 classrooms.

Ecology is one of the "must-teach" topics for any biology or life science class. The ecological inter-relationships that occur in nature are fundamental to an understanding of our world and how life interacts with the physical environment as well as with other living organisms. Ecology topics, such as global warming, ozone destruction, greenhouse gases, and habitat destruction, dominate the news. We must make sure that our students are knowledgeable in the basic principles of ecology so they can be informed decision makers in the future.

There is so much material to teach in a unit on Ecology that it can be overwhelming. I have divided the information into 6 separate units of instruction:

1. Introduction to Ecology

2. Population Ecology

3. Community Ecology

4. Ecosystems and the Biosphere Part 1: Energy Flow and the Recycling of Matter

5. Ecosystems and the Biosphere Part 2: Biomes of the World

6. Humans and the Environment

Please Note: This product is just for the third topic of instruction: Community Ecology

This colorful and engaging PowerPoint presentation will provide your students with interactive lessons on the ecology of communities. It consists of 56 slides that are colorful, informative and visually stimulating. Pictures and diagrams are included that will greatly enhance your instruction to your students. This product also includes a set of notes for the teacher (5 pages) and a "guided notes outline" for the student (7 pages). Graphics, diagrams, clip art, and photographs were chosen to capture the attention of the student as the lesson is being taught.

Topics covered in this lesson are:

  • Community Interactions: Definition of community, types of community interactions such as competition, predation, symbiosis, mutualism, commensalism, and parasitism.
  • Competition: Definition of competition, definition of resource, the competitive exclusion principle, character displacement, many examples, resource partitioning, the result of organisms having identical niches.
  • Predation: Definition, examples, predator, prey, the role of natural selection, adaptations found in predators, adaptations found in prey, mimicry, adaptations found in plants and herbivores.
  • Symbiosis: Definition of symbiosis, types of symbiosis, mutualism, commensalism, parasitism, many examples of each.
  • Properties of Communities: Species richness and diversity, definition of species richness, definition of species diversity, the species-area effect, the result of habitat destruction.
  • Succession: Disturbances, definition and examples of disturbances, definition of succession, types of succession, primary succession, examples of primary succession, secondary succession, examples of secondary succession, pioneer species, climax communities.
  • Succession in a Marine Ecosystem: A Whale-Fall Community.

This PowerPoint was written with a typical biology I class in mind. It can easily be edited to meet your needs.
