Succession
Pioneer Species
Asexual reproduction, so a single organism can rapidly multiply.
-
-
Ability to photosynthesise, so not dependent on animal species.
Ability to fix nitrogen from the atmosphere, as soil has few nutrients.
-
-
Secondary Succession
-
Human activities, such as farming and logging, can change landscapes.
Low growing plants will populate the area. Trees will appear and develop. Creates a mature forest faster than primary succession as soil was already present in the area.
Primary Succession
-
Moss would grow and break up the rock - creates soil. Seed dispersal would bring seeds to the new soil. Plants would start to grow. Over time, the once bare rock will become a mature adult forest.
Stages of Succession
At each stage, new species colonise the area and these may change the environment such that: the area becomes less suitable for the existing species - as a result, new species may outcompete the existing species. The area becomes more suitable for other species with different adaptations, which therefore can colonise and outcompete existing species.
These successional changes alter the abiotic environment. This can result in a less hostile environment that makes it easier for other species to survive. Therefore, new communities are formed and biodiversity may be changed/ increased to the climax community.
