I represents environmental variation that does not have catastrophic consequences but can impact individuals to some degree. III represents sudden catastrophes that kill off large numbers of individuals. Both of these are examples of environmental stochasticity. II, on the other hand, represents individual-level variation that is not strictly environmental stochasticity, as it is not caused by external forces but rather internal ones.
