Ecology Video on Succession
* Many factors impact an ecosystem
* Ecological succession is a process where a community transforms itself until it is a stable
* 2 types of succession
* Primary Succession: No previous vegetation or growth
* Secondary Succession: Previous vegetation/growth
An example of PRIMARY succession:
The image above is PRIMARY succession because there WASN'T previous growth or vegetation.

Here is an example of SECONDARY succession:
The image above is SECONDARY succession because there WAS previous growth/vegetation.

Early Colonizers
* Biotic/Abiotic factors influence succession
* Early colonizers are fast growing forms of vegetation
* Can adapt to amount of sunlight
* Wind dispersed
* Some early colonizers have symbiotic relationships with environment
