Primary succession begins on bare ground with pioneer species like algae improving nutrients and soil depth, making the environment less hostile for more complex species, which eventually outcompete the pioneers.
- bare rock/sand - initial environment lacks nutrients - pioneer species (normally algae) increases availability of nutrients - increases soil depth - named change to environment makes it less hostile - allowing complex species to survive - more effective competitor outcompetes pioneer species - excludes preceding species from community - replaces pioneer species
