I am still new to some basic ecological concepts. I am dealing with a certain sponge which can grow on rock, coral reefs, and macro algae. Say, if I want to find out the factor that shapes the symbiotic community in the sponge, can coral/algae be the biological factor for statistic analysis? Or do I need to find a specific interaction and to call that a biological factor? I just feel it would be too simple to call a coral/algae 'biological factor'.
