Organisms in Microcommunities

Define: Motile-moving organism.
sessile- stationary or not moving organism
Producer- makes own food and is food for other organisms.
consumer- Feeds on producers or other consumers.
Autotroph- makes own food from sun using photosynthesis.
Heterotroph- dose not make own food and feeds on autotroph.

Procedure: 1.Make a slide with the pond water 2. Observe the slide under the microscope with low, medium, and high power. 3. record the organisms you found.
Materials: Microscope, slides, and pond water.

Question: what organisms will u find in the pond water?
Answer: 1. Volvox. A volvox is sessile, a consumer, and is heterotrophic

2. Paramecium, is sessile, a consumer, and is heterotophic. 

3. Pinnularia. It is sessile, a consumer, and is heterotrophic.

4. Spirogyrd is a sessile, a producer, and is a autotrophic

 5. Rotifer is sessile, a producer, and autorophic

                                                      

6. Zygnema is motile, a producer, and autotrophic

questions: 1. What might the role of the microorganisms be in a fresh water community? They can be producers such as algae to feed fish. 

2.describe the process of preparing a wet mount. Take a slide, put what your observing on the slide, then put a drop or two of water on, then put on cover slip.

3. Differentiate between microorganism and micro-community. A microorganism is one organism and a micro community is multiple microorganisms. 



Owl Pellets

Logan Boggess

Period:1

Question: How many bones are in your owl pellet?

Prior knowledge: None

Protocol: 1. Gather materials: Owl pellet, tray, probing tools, and paper towel. 2. Unwrap owl pellet and measure length and width. 3. Examine pellet for fur or feathers. 4. dissect the pellet and remove all the bones. 5. Identify the bones. 6. count each type of bone.

Materials: Owl pellet, probing tools, tray, and paper towel.

Data/Results: Skulls: 3 Type: Bird, and mole. Jaw: 3 Type: rodent Scapula: 1 Type: Rodent. Forelimb: 20 Type: Mole. Hind limb: 12 Type: Rodent. Pelvic Bone: 2 Type: Mole. Rib: 32 Type: Rodent and Bird. Vertebrae: 13 Type: Rodent and Mole
