Trophic Pyramid Notes Lets make a trophic pyramid

Trophic Pyramid Notes Let’s make a trophic pyramid!

Here are the steps… 1. You will need three sheets of blank paper. 2. Fold the top of the first page down so that the paper is 8 inches high. 8”

Here are the steps… 3. Fold the top of the second page down so that the paper is 7 inches high. 7”

Here are the steps… 4. Fold the top of the third page down so that the paper is 6 inches high. 6”

Look at the teacher’s example – 5. Place the 2 nd page inside the 1 st page. 6. Now, place the 3 rd page inside the 2 nd page. Step 5. Step 6.

Label: 1. Find the center of the top of the 1 st page and draw a diagonal line to the bottom left corner. Draw another diagonal line starting at the same place to the bottom right corner. You have a triangle!!!

Within the triangle that you drew, label each tab of paper as follows: 2. Top tab of paper: “ 6 th Trophic Level - Top Consumer” 3. Label the next tab of paper: “ 5 th Trophic Level – Quaternary Consumers” 4. Label the next tab of paper: “ 4 th Trophic Level – Tertiary Consumers”

5. Label the next tab of paper: “ 3 rd Trophic Level – Secondary Consumers” 6. Label the next tab of paper: “ 2 nd Trophic Level – Primary Consumers” 7. Label the bottom tab of paper: “ 1 st Trophic Level – Primary Producers” 8. On the top tab of paper, write: “Trophic Pyramid Notes”

Take 1. Underneath each tab of paper, copy Notes: the notes for that trophic level from the Trophic Pyramid Notes which will follow. • Be sure that when all the tabs are lying flat you will not be able to see the notes. • Also, leave room to paste pictures of organisms in each trophic level.

Trophic Pyramid Notes 1 st Trophic Level – Primary Producers - Autotrophs - Always the bottom level - Produce energy by photosynthesis Examples: Grasses, Trees, Shrubs - Energy = 1000 J

Trophic Pyramid Notes 2 nd Trophic Level - Primary Consumers - Herbivores - Eat plants Examples: Grasshoppers, mice, insects - Energy = 100 J

Trophic Pyramid Notes 3 rd Trophic Level - Secondary Consumers - Eat Herbivores - May be Omnivores Examples: Small Birds, Snakes

Trophic Pyramid Notes 4 th Trophic Level - Tertiary Consumers - Could be carnivores or omnivores

Trophic Pyramid Notes 5 th Trophic Level - Quaternary Consumers - Carnivores - must eat a lot of prey to gain energy they require. Examples: bluefish, striped bass

Trophic Pyramid Notes 6 th Trophic Level - Top Consumers - Nothing eats them as living adults. - Always the top level Examples: bull shark, humans
