Ø Reaction is the most important stage in the ecological succession. Ø It is the modification of the environment through the influence of living organism present on it. Ø Reaction cause change in soil, water, light and temperature of the area.

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 emerges one after another until the Climax stage is reached.

The 5 stages of Ecological Succession in successive order are- Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization.

Ecological succession is the steady and gradual change in a species of a given area with respect to the changing environment. It is a predictable change and is an inevitable process of nature as all the biotic components have to keep up with the changes in our environment.

Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a “climax community”—like a mature forest—is reached, or until a disturbance, like a fire, occurs. Ecological succession is a fundamental concept in ecology.

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.

As ecological succession occurs, types of species (both plants and animals) present in a community will change in response to changing environmental conditions. Examples of such environmental conditions include fires, climate change, and human activities, such as clearing forests in order to plant farm fields.

The stages of secondary succession are as follows: A growing ecosystem exists. An event occurs that destroys a lot of the existing growth. The event stops, as does the destruction. The soil remains. Time passes. Regrowth starts to occur. Fast-growing plants and/or trees start growing.
