Trophic example

This is an example of a trophic interaction between the blacktail deer and their foraging of the stems and foliage of the blackberry bush. I would say the most influential species would be the monterey pine trees. The pine trees offer year-round shade for many of the lower lying plants that are successful in many of fully or partially shaded areas of the ecosystem, such as the many ferns, horsetails, and blackberry bush. If you were to remove all of the pine trees, many of the plants would eventually die off with the constant intensity of the sun bearing down on them. Many of these trees have already been replaced by an invasive species, the eucalyptus tree, and many of the plants mentioned above, do not grow as well under the canopy of the eucalyptus.

 

Three Species:

-Banana Slug: Hairston, Smith, and Slobodkin mentioned that decomposers must be food-limited, since they comprise the trophic level that degrades organic debris.

-Monterey Pine: It will be limited by interspecific competition, as we see already with them and the eucalyptus.

-Fungi species: It is also a decomposer, food-limited by their degradation of organic debris.
