Create your Tackk
1. Click on the green pencil icon in the top right corner and select “Blank Canvas”.
2. Select your color palette, font, and pattern in the expanded menu on the right side.
3. Under “Options”, check that it is “public” and add to the Tackkboard with the following tag:
Use EP[teacher][class period number] for this assignment.
ex: EPGunnip2, EPGunnip3, EPGunnip4, EPGunnip5, EPGunnip7
4. Once you have your first step done (Step 1 below), then publish your Tackk by clicking on the green publish button at the bottom of your screen.
Step 1: Choose an ecosystem and find a picture
1. Choose an ecosystem that you would like to research. Your should know a little about the ecosystem you choose.
2. Do a Google search for an image of your ecosystem that you can use for your portfolio. Your image should try to include plants and animals that live there.
3. Your first headline should be the name of the ecosystem you chose. Then you should upload the image.
Step 2: Identify the Biotic and Abiotic Factors in your ecosystem
1. Organize, define, and list both the biotic factors specific to your ecosystem and the abiotic factors specific to your ecosystem. You should have at least 5 biotic and 5 abiotic factors listed. They should be specific to YOUR ecosystem.
2. Include pictures or video to show one or more of these in each category.
Biotic Factors : Living factors in an ecosystem
Ram Arctic Willow
Musk Oxe Mosses
Arctic Wolf Caribou Moss
Arctic Hare Bearberry
Arctic Fox Pasque Flower
Caribou Labrador Tea
Grizzly Bear Tufted Saxifrage
Abiotic Factors: Non-living factors in an ecosystem
Citing your sources
1. Add a caption (directly under the image) to each picture with the name of the site you got the picture from. (example: Google, Instagram) If you got the image from Tackk, it is already sited for you so you do not have to add a caption.
2. Add a "Button" under each section to cite the source of your information. Customize the label of the button with the name of the website, then copy and paste the URL and click "apply" for the button to link to your source.
Step 3: Habitat Resources
1. Explain how a population specific to your ecosystem changes over time depending on the availability of habitat resources.(think about Oh Deer! or the moose/wolf graph and relate it to an animal population in YOUR ecosystem) Make sure you list the 4 habitat resources.
2. Find or create a graph or some other visual aid (picture/video) to help illustrate this idea.

3. Identify a specific predator/prey relationship in your ecosystem and describe how limiting factors can affect one or more of these populations.
Be sure to identify what the limiting factor is and which population is DIRECTLY impacted and which is INDIRECTLY impacted because of the limiting factor.
4. Add pictures or other visual aids to illustrate this idea from #3 above.
Step 4: Energy Roles
1. Define each of the Energy Roles. Give an example of each energy role specific for your ecosystem. Make sure you include the different types of consumers (herbivore, carnivore, omnivore, scavenger)
2. Explain from where each of the energy roles recieve its energy.
3. Insert pictures/video to show some of these organisms. (at least 3 pictures/videos)
4. Explain the role of producers in the transfer of energy coming from the sun. (Why are producers vital to any ecosystem?)
Step 5: Food Chains and Food Webs
1. Find or create a food web for your specific ecosystem.
2. Explain why food webs are more reaslistic than food chains for your ecosystem.
3. Explain what would happen if you removed one population from your food web. What effects would that have on other populations?
Step 6: Trophic Levels and Energy Pyramids
1. Find OR create an energy pyramid for your ecosystem using some of the organisms from your food web. You should have the name OR a picture of the organisms in the correct trophic level.
2. Label the trophic levels and include the approximate amount of energy available at each level. You may also color code your levels if you wish.
3. Explain the reason behind the use a pyramid shape rather than some other shape like a cylindar or cube. (What does the pyramid shape show about the energy?)
4. Explain why producers are in the largest level (base) and top predators are in the smallest level. (What does this represent?)
YOU ARE DONE!!! Almost.... ;)
1. Go back and check spelling, grammer, capitalization, and punctuation in EVERY section.
2. Check all pictures and make sure they are clear. If they are blurry, you need to think about replacing them with a clear picture.
3. Check that you have correctly cited ALL of your sources. (Captions for pictures and buttons for information.)
3. Go back and check ALL 6 STEPS and make sure you have a headline for each step, ALL of the details from my instructions, and a picture or video for each step.
