Succession of the Ecosystem The theory of evolution is arguably the oldest theory used world over by scientists to explain the differences that exist between organisms of similar species. The theory states that the environment is harsh and only the fittest organisms survive. Therefore only organisms with desirable characteristics live to reach maturity and therefore mate. Desirable characteristics include those basic traits as strength, resistance to diseases among others. These animals that are better adapted to the environment pass these desirable traits to their off springs. These offspring also get to develop better traits than their parents. As per this theory, those unfit organisms while their better colleagues reach maturity, die and do not get the chance to produce off springs. This leads to extinction of such organisms.
This explanation around evolution leads to succession. This is a simpler logic of the habitats being inherited by the offspring of older generations. Traits are passed from parents to off springs and this in basic terms defines succession. Succession is further categorized into two and this includes primary and secondary succession. The primary is one in which succession begins in an absolutely new environment. This succession is therefore uninfluenced by pre existing communities. This takes place after migrating from one habitat to another and the organisms start survival afresh. The laws of natural selection set in and only those with better traits get the chance of adopting and surviving in the new habitation. Primary selection in combination with natural selection explains the differences that exist between organisms of a single specie. At that is similar organisms develop different survival mechanisms that characterizes their ecosystem
Secondary succession on the other side is one in which succession follows the disruption of a pre existing community. When a habitat is hit by a calamity, such as a fire that consumes an entry territory, plants and bacteria start life afresh and this constitutes secondary succession.
In the succession animation provided on the course work, it is an example of primary succession. By and large, the traits that lead the development from one organism to another is that picked and developed from the parent organism. The offspring is therefore always with better survival traits than the parent and some what differ from the fore parents owing to the adaptative traits that they succeedingly acquired.
