how long can primary succession take to be completed
Weegy: 500 Years Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and usually lacking soil, [ such as a lava flow or area left from retreated glacier, [ is deposited.n other words, it is the gradual growth of an ecosystem over a longer period of time. In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance such as forest fire, tsunami, flood, destroyed the plant life.
