Succession• Orderly change over time of natural

species replacement in a community or ecosystem

Page 10: Warm Up Shown here is some lichen on a rock.. A. What is lichen? B. What type of biotic interaction would it be classified as? Why? C. What role does

Succession communities:

1. Pioneer species

2. Intermediate species

3. Climax community

Page 11: Warm Up Shown here is some lichen on a rock.. A. What is lichen? B. What type of biotic interaction would it be classified as? Why? C. What role does

Pioneer species:

• Lichens (algae & fungi) break apart rock to make soil

• Grasses• Annual flowers• Mosses

Climax Community: final set of organisms suited to that climate

Types of Succession

Primary

• 1st time plants

or animals are

established

• New island

• Volcanoes

• Glaciers

• Bare soil, rock

Secondary• After a “blowout”• Re-establish a

community• Already had

living organisms• Fire, flood,

human disruption

New island= Primary Succession

Page 15: Warm Up Shown here is some lichen on a rock.. A. What is lichen? B. What type of biotic interaction would it be classified as? Why? C. What role does

Secondary Succession will follow!

Primary Or Secondary?

Page 17: Warm Up Shown here is some lichen on a rock.. A. What is lichen? B. What type of biotic interaction would it be classified as? Why? C. What role does

BOTH PRIMARY & SECONDARY have

these Succession communities:

1. Pioneer species

2. Intermediate species

3. Climax community
