How long might it take for an ecosystem to become balanced?

Ecological balanced refers to the condition of dynamic equilibrium in a community of organisms in which the species,  the diversity of ecosystem and  the genetic pool remain  relatively constant  as a result of gradual changes that are brought about by natural selection. It is very important to ensure that the natural balance in an ecosystem is maintained. Typically, an ecosystem has to move through series of successional changes before it can reach the state of equilibrium. FOR AN ECOSYSTEM TO BE BALANCED, IT WILL TAKE BETWEEN THIRTY TO ONE HUNDRED YEARS depending on the type of ecosystem involved.
