This PowerPoint was one very small part of my Ecology Interactions Unit from the website http://sciencepowerpoint.com/index.html .This unit includes a 3 part 2000+ Slide PowerPoint loaded with activities, project ideas, critical class notes (red slides), review opportunities, challenge questions with answers, 3 PowerPoint review games (125 slides each) and much more. A bundled homework package and detailed unit notes chronologically follow the PowerPoint slideshow. Areas of Focus within The Ecology Interactions Unit: Levels of Biological Organization (Ecology), Parts of the Biosphere, Habitat, Ecological Niche, Types of Competition, Competitive Exclusion Theory, Animal Interactions, Food Webs, Predator Prey Relationships, Camouflage, Population Sampling, Abundance, Relative Abundance, Diversity, Mimicry, Batesian Mimicry, Mullerian Mimicry, Symbiosis, Parasitism, Mutualism, Commensalism, Plant and Animal Interactions, Coevolution, Animal Strategies to Eat Plants, Plant Defense Mechanisms, Exotic Species, Impacts of Invasive Exotic Species. If you have any questions please feel free to contact me. Thank you again and best wishes. Sincerely, Ryan Murphy M.Ed www.sciencepowerpoint@gmail.com
