Ecological Succession Flipbook From Rocks to Soil, From Lichen to Forest!
Sahara desert !!
By Kenta Tsukui Science 10 November 21
Sahara desert starts when there is place with no soil at all. Also there are no plants or animals present in this stage.
Soil: non-existent Species diversity: none Trophic levels: none Niches: none Nutrient Recycling: none
Primary Succession Stage 1: Pioneer Species
Stage Info: Lichens arrive and started to create soil. But pioneer species do not need soil to live. So, they just create it.
Soil: simple Species diversity: only lichen Trophic levels: 1 producer Niches: extremely simple Nutrient recycling: minimal
Small plants and moss start growing.
Soil- low Species diversity – low Trophic levels – 1 Niches – few Nutrient recycling - few
There will be a lot of soil for new plants to grow and survive. The cacti growing tall, but grass is short.
Species diversity: Trophic levels: Niches: Nutrient recycling:
has sandy soil, mostly dry sand rich 3 extremely complex extensive, complex
When a fire, burns an area of forest. All plants and animals gone. But all soil still there.
Soil- high Species diversity â€“ low Trophic levels - none Niches â€“ none Nutrient recycling - none
After a fire, burns an area of forest. The soil is all that’s left but it already contains the seed needed to grow new plants. It takes a lot of time to climax community.
Soil – high Species diversity – low Trophic levels – 1 Niches – few Nutrient recycling - few
The Saharaâ€™s factors Biotic -Camels -Cacti -Scorpions -Owls -Coyotes
Abiotic -Sunlight -Sand -Oxygen -Carbon dioxide -Water -Rocks
