- The combination of all the external conditions and the potential effect of the inner environment (heteromosaic of abiotic conditions). e. change: survival depends on the life span of the organisms involved, and has to adapt to a new situation via genetic change, evolution, etc. • cyclic change: rhythmically repetitive, like cycles of a season, day / night, movement of tides etc. • directional change: change is maintained over a long period in relation to the life span of organisms - erosion, siltation, cycles of glaciation, etc. • erratic change: these have no rhythm and no consistent direction e.g., hurricanes, cyclones, flash storms, fires, vulcanos, earthquake, etc.
