Succession

what does the term succession means ?

A change in s habitat from bare rock to a climax community.

how does the primary succession goes. Draw a flow chart.

Bare rock → licken → mosses → grasses → shrubs ( baddlea ) → trees ( silver birch ) → mature oak woodland ( climax community ).

what prevent primary succession occurs ?

unless its interrupted or deflected eg : by grazing or mowing.

How does deflected succession occurs

It occurs by grazing or mowing to form a plagioclimax.

how does the primary succession goes. Draw a flow chart.

Grasses → shrubs → mature oak woodland

when does secondary succession occurs ?

Occurs after destruction of a habitat eg : by forest fire that had previously undergone succession therefore soil already exist, so clary stage of succession don’t need to occur.

Outline the process of primary succession part 1

Pioneer community → bare rock arrival seed or spores + Pioneer species have certain adaptation ( nitrogen fixation )

Intermediate community → Herb species ( grasses ) + followed by shrubs

Outline the process of primary succession part 2

Climax community → Little change over time, dominance by few trees

General principle → Seral stages , community / decomposition changes the composition oof soil

Increased organic nitrate or water content

what does deflected succession means ?

Climax community is prevented from developing = plagioclimax
