1. Mind Stretcher 8/30/17
Name at least 3 ways we depend on other organisms OR our environment for survival…
Need Environment- Water, shelter, space
Need Organisms- Food (eat animals, plants, fungi, etc.), Pets/companionship…

2. Directions Today: Discuss Ecology 2 Learning Plan & hook into notebook
Ecology 2 Pretest- Mark “E” if you do NOT know an answer
DO NOT WRITE ON TEST
Turn in test copy and scantron to front desk
Read Ch. 18 section 3 silently OR work on yellow remediation sheet if you plan on retaking Ecology 1 test tomorrow!

3. 8/31/17 On a new sheet of notebook paper, copy the following…
Competition
_______________: when two or more organisms rely on the same environmental resource
Predation
_______________: behavior of one animal feeding on another
Symbiosis
______________: close relationship of two dissimilar organisms in which one always benefits

4. SYMBIOSIS
MUTUALISM
PARASITISM
COMPETITION
PREDATION
COMMENSALISM

5. Where do these words come from??
SYMBIOSIS- "state of living together."
PARASITISM- Greek parasitos "one who lives at another's expense”
MUTUALISM- mutuus = reciprocal, done in exchange
COMMENSALISM- Latin commensalis, meaning "sharing a table", from the prefix com-, meaning "together", and mensa, meaning "table" or "meal".

6. Where do these words come from??
COMPETITION- from compete: " to enter or be put in rivalry with,"
PREDATION-
"act of plundering or pillaging," (predator/prey)

7. Quickly write the 3 TYPES of Symbiosis on your same sheet of notebook paper…
Symbiosis: (3 types)
mutualism— BOTH organisms benefit
commensalism— one organism benefits and one is unharmed/unaffected
parasitism—one organism benefits and one is harmed

8. Why would this be beneficial?
Crittercam
GOAL: to help researchers understand the day-to-day lives and ecological relationships of different species.
PROCESS: fit wild animals with a GPS tracker and a combination video and audio recorder with environmental data instruments to measure such things as depth, temperature, and acceleration
WHY: allows the study of animal behavior without interference by human observers
Why would this be beneficial?

9. Crittercam Video Discussion: http://nationalgeographic
Watch video clip: “Fish Thieves Take Rare Seals’ Prey”
What is the ecological relationship between the monk seal and the octopus/eel/trigger fish?
Predator/Prey (predation)
What is the ecological relationship between the monk seal and the jacks/sharks?
Competition

10. Crittercam Video Discussion:
What symbiotic relationship is occurring in each of the following videos?
MUTUALISM
“Caribbean Cleaners” (2.5 minutes)
“Giving Fish a Bath” (5.5 minutes)
“Clownfish and Sea Anemone Partnership” (1.5 min)
PARASITISM
MUTUALISM
Which relationship was not demonstrated?

11. Lemon Shark
Other than the shark, what other organisms do you observe?
It was because of this relationship that Greg Marshall, marine biologist and filmmaker, invented Crittercam. In 1986, a shark approached him during a dive near Belize. Marshall noticed a remora clinging to a shark, and as he watched the shark disappear, it occurred to him that if he could put a camera in the place of the remora, he could see the shark's behavior unfold without disturbing the shark.

12. Why do they do this?
Remoras attach themselves to predatory fish like sharks for a few reasons:
1- a free ride
2- protection due to hanging onto a feared predator
3- feed off of food scraps left behind by shark
The shark is not affected in the process since remoras eat only leftover food from the shark… (Commensalism)

13. Symbiotic Interactions Worksheet
Complete the student sheet
Make sure to explain WHY you classified the different scenarios as one type of symbiosis and not the others…
How do ecological relationships shape the marine ecosystem? Why is it important to identify and understand these relationships?

14. Mind Stretcher 9/1/17 Name 3 types of relationships between organisms.
Predation (Predator/Prey)
Competition
Symbiosis
Coevolution
