i think population is all the organisims of a particular species in a habitat whereas community is all the organisms of all the species in the environment.

Community= All the different species living together in a particular area.
Population= All the organisms in a particular species living together in a particular area

1.Community
2. Ecological Niche
3. Interspecific competition
4. Migration (possibly)
b. Bare land being populated by a pioneer species, which is replaced by larger plants/shrubs, these die, decay build up humus (organic matter) in the soil, making it more stable and allowing trees and stuff to grow. As succession occurs, more insects/animals will populate, and the ecosystem becomes more stable.
