Succession (AQA A-Level Geography): Flashcards

Changes in community composition over time; increases complexity

Completely fresh surfaces with no soil or organic matter

Previously inhabited but disturbed areas; soil already present

Succession beginning on newly exposed bare rock surfaces

Succession starting on bare sand (e.g. coastal dunes)

Succession beginning in freshwater (e.g. ponds/lakes)

Succession starting in saltwater (e.g. salt marshes)

First organisms to colonise barren areas; survive harsh conditions

Final succession stage; maximum development under local climate

Soil & organic matter already exist, giving it a head start
