1. How do organisms of the same species interact with each other? Turn in: reflection paragraph Write down your homework in your planner

2. What are three major types of interactions among organisms? There are three major types of interactions among organisms: 1.Competition 2.Predation 3.Symbiosis Turn to your elbow partner and explain an example of competition

3. Competition Competition is the struggle between organisms to survive as they attempt to use the same limited resource. In any ecosystem, there is a limited amount of food, water and shelter. How does this relate to carrying capacity? Density dependent or independent? What is competition? What do organisms have to do in order to reduce competition?

4. Predation Predation is an interaction in which one organism kills another for food. The organism that does the killing for food is the predator. The organisms that is killed for food is the prey. What is predation? What is the relationship between predator and prey?

5. Symbiosis Any relationship in which two species live closely together

6. Finding Nemo On the back of your notes sheet, list as many interactions as you can. Label them as competition, predation, or symbiosis. http://www.cleanvideosearch.com/media/acti on/yt/watch?videoId=ufxGw8EqY5Q http://www.cleanvideosearch.com/media/acti on/yt/watch?videoId=ufxGw8EqY5Q Remember to think of ALL living thngs.

7. Three types of symbiosis Mutualism – both species benefit Commensalism – one species benefits, the other species is not affected Parasitism – one species benefits, the other species is harmed What type of symbiosis was happening between the bee and the flower on the previous page??

8. Three types of symbiosis Mutualism- both species benefit

9. Mutualism: Zebra and zebra finch

10. Three types of symbiosis Commensalism- one species benefits, the other is not affected

11. Commensalism: whale and barnacles

12. Three types of symbiosis Parasitism- one species benefits while the other is harmed

13. Parasitism: human and mosquito

14. Checkpoint Can relationships between species change over time? Give a specific example of a relationship shifting between mutualism, commensalism, and/or parasitism.

15. What relationship is…..?
