Succession- Lesson

Succession

​

Multiple Choice

Succession is...

• the gradual change of an ecosystem.

• the destruction of an ecosystem

• the takeover of invasive species.

• the passing of a royalty title in fuedalism.

Primary Succession

Primary Succession

• Lichens and moss (pioneer species) appear

• Erosion breaks rocks apart into smaller pieces and decomposition of pioneer species adds nutrients to the ground (soil formation)

• Small annuals (plants) start to appear

• Grasses and ferns (perennials) appear

• Shrubs and bushes appear

• Softwoods such as conifers (trees with cones) appear

• Hardwoods such as oak, maple, hickory, walnut, and cherry trees

Climax Comminuty

Eventually a community reaches a steady with relatively no change which is called a climax community.

Multiple Choice

What is formed during primary succession that doesn't need to be formed during secondary succession?

• pioneer species

• soil

• climax community

• lichens

Multiple Choice

Multiple Choice

Multiple Choice

What are examples of pioneer species in a primary succession?

• Bushes and Shrubs

• Oak trees

• Mossess and Lichens 

• A rose Bush

Multiple Choice

After a volcanic eruption, volcanic rock is present (but no soil). Which of the following states the most likely order of succession that would be seen?

• Lichens → Shrubs → Grasses → Trees

• Lichens → tree → shrubs→Grasses

• Grasses → Lichens → Shrubs → Trees

• Lichens → Grasses → Shrubs → Trees

Secondary Succession

Process in which recolonization of plants occurs after some kind of natural disaster such as a forest fire.

Quicker than primary succession since the soil still remains.
