Transcript of The Wolf, the Moose, and the Fir Tree: A Case Study of Troph

The Wolf, the Moose, and the Fir Tree: A Case Study of Trophic Interactions

It is control exerted from the top down because in the primary productivity hypothesis the changes in organisms are proportional while in the trophic cascade model there are reversed proportions. Lastly in the data when the moose's population increases the fir tree ring's length decreases because the moose eats the bark of the fir tree but when the moose's population decreases the fir tree ring's length increase.
5. What final conclusions can you draw about the interactions between each trophic level on Isle Royale?

Answer #1
The final conclusion that I can draw about the interactions between each trophic level on Isle Royale is that the trophic cascade model's hypothesis is that changes in one trophic level is caused by opposite changes in the other trophic level right above it.



5.
Is control exerted from the top down, as suggested by the trophic cascade model, or are interactions between
trophic levels ultimately controlled by primary productivity?
