Question

Different types of ecological succession

Answer 1

The 3 stages of ecological succession are:

1.Primary – This is when an ecological community first enters into a new form of habitat that it has not been present in before. A good example of this would be the habitat created when granite is removed in a quarry. The rock face that is left behind is altered and becomes a new habitat. The environment that then grows within that habitat is considered to be in its primary stage.

2. Secondary – The secondary succession stage occurs after a habitat has been established, but it is then disturbed or changed in some fashion and a new community moves in. To use the example from before – let us say that a primary stage develops on the face of a newly quarried granite cliff. That habitat grows undisturbed, until there is a forest fire that then burns and changes a portion of the habitat that has been growing on the rock face. That ecological habitat has now entered its secondary stage.

3. Climax – the climax stage is the last stage of an ecosystem. It is when the ecosystem has become balanced and there is little risk of an interfering event or change to mutate the environment. Several rainforests and deserts qualify as being in the climax stage.

Pioneer – pioneer types are the new lifeforms that enter into a primary succession and begin to take hold. This can be anything from a seed to a bacteria to an insect or to an animal wandering into a new area and bedding down to make it their home. The pioneer has no connection to the environment, but it does find enough present in the new ecosystem to begin to establish its life.
Establishing – the establishing type can be hard to pinpoint because it crosses into the pioneer and sustaining. Establishing is the process in which lifeforms identify elements in an ecosystem that can sustain their basic needs – such as food, water and safe habitat.
Sustaining – Sustaining type means that life in the ecosystem has begun to enter into a pattern that allows for a cycle of life to continue. This means that birth and death are occurring, and there is little migration outside of the ecosystem – this is most common in the climax succession.
Producing – the producing type occurs during the secondary succession. This is when lifeforms are breeding and growing, but there is migration because what is produced is also not capable of being supported within the ecosystem. 

Answer 2

                   Ecological Succession                          

Ecological Succession is a change in the structure of Natural organism or any other kind of matter in Ecosystem. For Ecological Succession Thousands and Millions of Years are required.                   

Ecological Succession is a very slow process. It is just a process like Evolution. We can't say that Ecological Succession and Evolution are same. They are bit different.

                    

Best example of Ecological Succession is Human Beings. According to our History books, we know that Humans were first were like Monkeys. And after that, Humans were Evolved very Rapidly. Some Scientists also believe that, Humans were Have tail on the Back.

Ecological Succession is a very slow process. In this Ecological process, Organism is adapted according to the Nature around it.Parts of Body which we don't need are removed from our body in this process.

There are 2 types of Ecological Succession:

i) Primary Ecological Succession

ii) Secondary Ecological Succession
