1. Food Webs and Chains- Using the Assure Model Presenters: Bunantie Cain Alecia Harris Date: May 3, 2013. Course: Educational Technology Facilitators: Mrs. Jack Ms. Williams

2. Objectives Define food chain and Web Identify the different organisms found in a food chain and web Construct a food chain and web and present construction either by a PowerPoint Presentation, Movie using Windows Maker, or by using Google Drive

3. Instructions  Type the following into your URL: http://lifescis.weebly.com Then go to the section on food chains and web Then click on lecture notes

4. Food Chain  is a linear sequence of how energy is passed from one organism to the next within an ecosystem.

5. Composition of a food chain

6. Food Web  An interconnected food chain  Based on a what eat what principle  This is what truly exists in any ecosystem  No one organism can be sustained by just only one other organism

7. Food Web

8. Assignment one Go to the video section of the website under the column “Introduction” Watch the first video “ food chain” and then watch the second video on food web Form three groups of five and then define a food chain and web

9. Organisms in a food chain and Web  Producers- makes their own food  Consumers- do not make their own food, but consume foods that have already been made Different types of consumers: Carnivore- eats only other animals Omnivores- eats both plants and animals Decomposers- feeds on dead and decaying matter - Primary consumer/ herbivore- eats only plants alone - Secondary consumer/ carnivore- eats only animals - tertiary consumer- feeds on the secondary consumers

10. Feeding Relationships within a food Chain/ Web  There are many different types of feeding relation that exist within any ecosystem  One such relationship is- Predator / Prey  Predator- stalks and hunts and another organism for its food. Predators are normally top carnivores  Prey- is hunted by the predator

11. Assignment two- 2  Please go to the column “more” on the home page of the website  Then select and follow the instructions given under assignment # 2

12. Assignment three - 3  Go to the slide show panel under introduction column of the website and view the slide show that is posted.  Then go to assignment number three and complete the task given.  You must complete the task given with one of the organisms presented within the slide show

13. Evaluation  Go to the Blog section and write what you think of the presentation, as well as, the learning experience.

14. Use of the Assure Model Please visit the “ notes” section on the website to see how this model was in cooperated within the lesson.

15. Conclusion  Summary  A food chain is a linear sequence of how energy is passed on from on organism to the next in a food chain  A food web is an interconnected food chain  Types of organisms found in a food chain and web are: Producers Consumers : -Primary consumers/ herbivores -Secondary consumers -Tertiary consumers -Decomposers -Predator -Prey
