Arrange the stages of ecological succession in the sequence in which they occur.
migration
reaction
nudation
ecesis
stabilization
competition

The stages of ecological succession is as follows:

nudation→migration→ecesis→competition→reaction→stabilization.

Explanation:

Ecological succession is a natural process by which some locality becomes successively colonized by different groups or communities.

The complete process of succession involves certain steps namely-

Nudation- Development of a bare area without any life form.Invasion- Establishment of species in a bare area, this process occurs in three successive stages:

         a) Migration, spreading of seed, spores etc.

          b) Ecesis ,Establishment of species.

          d) Aggregation.

Competition and coaction- Interspecific or intraspecific competition for space and nutrition. Individual species affecting each other life form is called coaction.Reaction - It is the modification of environment by organism.Stabilization- Finally the community becomes established for longer duration of time.If not replaced by new community then this community is known as climax community.
