Biology/Pre-AP Biology
International Scholars Academy

2. Monday 9-9-13 Due: Vocabulary ( unit 2), Promotional Claims Lab Report
Objective: Interpret relationships, including predation, parasitism, commensalisms, mutualism, and competition among organisms.
Agenda:
Bell Work 3 ( Level of Organization Practice) – 4min
Symbiotic Relationships Review/Journal Entry (journal headings) – ( 12R-14L)
Clean up/Pack up- Leave Journals for Grading
Ecology Vocabulary Test Thursday

3. Question ( 12L)

4. By the end of this PowerPoint, you should be able to answer…
What is symbiosis?
What are the different kinds of symbiosis

5. Journal Set- Up ( 12R-14L)
Headings 12R- Commensalism 13L-Mutalism 13R- Parasitism 14L- Predation Under each heading, you will paraphrase the meaning of each symbiotic relationship

6. Literal definition: the act of living together
What is symbiosis?
Literal definition: the act of living together
What it means:
Two organisms that live together
Temporarily or for a longer time
At least one of the organisms benefits from the relationship

7. What are the different kinds of symbiosis?
Mutualism
Commensalism
Parasitism
both organisms benefit
one organism benefits
one organism benefits
one organism is unaffected
one organism is harmed

8. “Good for you, good for me!
MUTUALISM
“Good for you, good for me!
Example: Ostrich and Gazelle
These two animals feed next to each other in the grasslands. Both watch for predators and alert each other to danger. The visual abilities of these two animals are different so they are able to identify threats the other animal would not see.

9. COMMENSALISM “Good for me, doesn’t bother you!
Example: Hermit Crab and Snail
Remora and Shark
A hermit crab lives in shells that are made and then abandoned by snails. This neither harms nor benefits the snail.
A remora attaches themselves to a shark’s body. They travel with the shark and feed on the left over food from the shark’s meals. This does not hurt or help the shark.

10. Parasitism “Good for me, hurts you!” Example: Cuckoo and Warbler
Deer and Tick
A cuckoo may lay its eggs in a warbler’s nest. The cuckoo’s young will displace the warbler’s young and will be raised by the warbler.
A tick feeds on deer blood to the detriment of the deer.

11. Predation
A form of symbiotic relationship between two organisms of unlike species in which one of them acts as predator that captures and feeds on the other organism that serves as the prey.

12. Parasitism: one benefits, one is harmed
Example 1: Acacia plant with ant galls
Ants lay eggs on acacia tree Acacia covers the infected area with brown flesh (gall)
Parasitism: one benefits, one is harmed

13. Mutualism: both benefit
Example 2: Moray Eel with Cleaner Fish
Moray Eel gets a clean mouth Cleaner Fish gets a meal
Mutualism: both benefit

14. Commensalism: one benefits, one is unaffected
Example 3: Cattle with cattle egrets
Cattle stir up insects as they eat grass Egrets hang around and eat insects
Commensalism: one benefits, one is unaffected

15. Commensalism: one benefits, one is unaffected
Example 4: Clown fish with anemone
Clown fish gets protection Anemone is unaffected
Commensalism: one benefits, one is unaffected

16. Mutualism: both benefit
Example 5: Antelope with Oxbird
Antelope gets rid of parasites Oxbird gets a meal
Mutualism: both benefit

17. Predation: The owl is hunting the mouse
Example 6:
Barn Owl Capturing Prey
Predation: The owl is hunting the mouse

18. Parasitism: one benefits, one is harmed
Example 7: Taenia worm in human eye
Worm infects human blood stream Human may go blind
Parasitism: one benefits, one is harmed

19. Instructions
Read the relationship described on each card. Determine what type of relationship this is and record the name of the organisms on the correct page in your journal. When you have all your cards completed, use glue or tape to post your cards on its page. VERIFY your answers before gluing/taping.

20. Tuesday 9-10-13- Tomorrow, Meet in the Library!!
Objectives:
Interpret relationships, including predation, parasitism, commensalisms, mutualism, and competition among organisms.
Compare variations and adaptations of organisms in different ecosystems.
Analyze the flow of matter and energy through trophic levels using various models, including food chains, food webs, and ecological pyramids.
Recognize that long term survival of species is dependent on changing resource bases that are limited.
Describe how environmental change can impact ecosystem stability.
Agenda:------****Vocabulary Test Thursday****
1. Bell Ringer 4 ( 14R)- 8 min
2. Symbiosis Cards (finish)
3. Engage For PBL:
