Trophic Interaction

The trophic interaction is of moss taking in sunlight and nutrients to create its own food since it's a primary producer. I think the most important species in my area is the Oak Tree. They are by far the most common tree at my site. They determine how much sunlight and rainfall enter the area since they make up the majority of the tree canopy at my site. They also affect carbon and oxygen levels at my site. If Oak trees were removed, there would be a huge shift at my site. Other species of trees would have to compete for spots in the canopy. Until other trees could fill the area, there would be a lot more sunlight and rain than the area would be used to which could be detrimental to some species. If an invasive species cam in there would be a lot of the same effects. It would make it very difficult for the many organisms that depend on the Oak trees for their habitat. The three organisms I chose to look at while reading the article were lichen, fern, and iris. The lichen is limited by access to sunlight. They have to grow in an area where they are not blocked by other ground plants. The fern is limited by nutrients from the ground and sunlight since they need these to do photosynthesis. This Iris is also a primary producer and is limited by sunlight and nutrients. My question for my site is how many species can be found on my 30X30 m plot of land and what does the food chain look like?
