A Late Stage Biome

[Don Schaeffer]

There are two stages in the growth of a biome: early stage and late stage. In the early stage there are lots of active organisms moving the chemistry of the microbe environment. In the late stage, the life process slows down or stops. The shapes of organisms remain inactive or minimized in the water as if the population of the biome are like ghosts, stop moving or move very little and enter a stage of gradual collapse and decay.
