Detailed explanation-1: -Climax. The last stage of ecological succession is the formation of a climax community. There is minimal resource competition and no further replacement of dominant plant species.

Detailed explanation-2: -The final stage is called the Climax Species. This is when the ecosystem has the most biodiversity. Over time, the previous phase organisms die off due to competition.

Detailed explanation-3: -The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.

Detailed explanation-4: -Succession occurs in stages that are can be seen in all environments. Their are three main forms of succession: primary succession, secondary succession, and cyclic succession. Seral communities and climax communities occur in the intermediate stages of succession.

Detailed explanation-5: -The 5 stages of succession are Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization. At the same location, a succession of biotic communities naturally emerge one after another until the Climax stage is reached.
