Trophic: Willow(Salix bonplandiana) leaves under decomposition

At this moment,the most influential species in my location would be Raphanus sativus , same species with radish. My site is covered by this species, and other organisms like bees, flys, and hummingbirds are coming my site for the nectar of the flower of radish. If it was removed, I think other species, maybe blackberry or English Ivy (because they are competing for space with radish) will take the space immediately. If blackberry won, I don't think that makes big change on my site, however, in the case of English Ivy take over the place, the soil would become more moisture since they shut the sunlight more than the radish, and population of insects that favor the dark and moist will increase.

About three organisms, I take snail, bee, and bryophyte.

Sails are the herbivorous so they are limited by the predetors and parasites. Beetles and birds might eat snails and Leucochloridium is the well-known parasite of snails.

Bees are the also herbivorous and limited by predation. Bees are not eaten by other insects, and most of the birds don't attack them too, but bee-eaters eats bee.

Bryophyte are producer and they are limited by resources, especially the light and water.
