Ecological Succession Flipbook From Rocks to Soil, From Lichen to Forest!

Sahara desert !!

By Kenta Tsukui Science 10 November 21


Bare Rock

Sahara desert starts when there is place with no soil at all. Also there are no plants or animals present in this stage.

Stage Info:

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


Early Colonizers

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.

Soil:

Stage Info:

Species diversity: Trophic levels: Niches: Nutrient recycling:

has sandy soil, mostly dry sand rich 3 extremely complex extensive, complex


Disturbance

When a fire, burns an area of forest. All plants and animals gone. But all soil still there.

Soil- high Species diversity – low Trophic levels - none Niches – none Nutrient recycling - none


Secondary Succession

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 Sahara’s factors Biotic -Camels -Cacti -Scorpions -Owls -Coyotes

-Lizards

Abiotic -Sunlight -Sand -Oxygen -Carbon dioxide -Water -Rocks
