Ecological Succession Powerpoint

This area is bare rock because it was originally attached to the mountain but over the years corrupted and finally fell off

Bare Rock

Stage 1 Pioneer Species

At this stage lichen were being Carried through the air and landedOn these rock and they would start To break the rock down and the dead Lichen would have given nutrients for The future plants to grow

Soil: simple and very thinSpecies diversity: lichen onlyTrophic level: 1 producerNiches: very simpleNutrient recycle: minimal

Stage 2 Early ColonizersSoil: tiny bit deeper still not so rich Species diversity: fewTrophic levels: 2Niches: low getting higherNutrient recycle: little

In this stage plants are starting to grow through theCracks in the rock on the some what soil.
