Terms in this set (77) Population ecology. Hi all. Population ecology - Population ecology - Species interactions and population growth: Community-level interactions are made up of the combined interactions between species within the biological community where the species coexist. First, let's review biotic and abiotic factors. The effects of one species upon another that derive from these interactions may take one of three forms: positive (+), negative (–), and neutral (0). STUDY. Chapter 6; 2 Levels of complexity. Community Ecology. Biotic factors are living organisms, an example would be a deer. For example, there may be one population of painted turtles in one state and another population of painted turtles 250 miles away in another state. Population and Community Ecology. Spell.
