Ecological Succession Lesson

Draw

Predict the Correct order of events

We will discuss and describe primary
and secondary succession

I will describe the difference between
primary and secondary succession

Write the “I will” in Notebook

- predictable sequence of events

Multiple Choice

What is the process called when a community of organisms slowly replaces another?

• Ecology

• Ecological Succession

• Primary Succession

• Secondary Succession

Your Warm-Up was an example of Succession

-No plants or animals existed in the area

When LAVA cools down, it hardens and turns in to

rock

Pioneer Species

Starts with nothing, then grows plants and animals over time

Multiple Choice

Primary Succession starts with

• Lichens and mosses

• Bare Rock

• Trees

• Soil

Multiple Choice

What is an example of a pioneer species in Primary Succession?

• Bare rock

• Moss & Lichen

• Grasses then shrubs

• Small trees then large trees

Multiple Choice

What is a pioneer species?

• stable point where few new plants colonize

• first organisms to live in an area

• process by which a community of organisms slowly replaces another

Which of the following shows a climax community? Justify
your answer.

Multiple Choice

What is a climax community?

• the first organisms to live in an area

• when the community reaches a stable point where few new plants colonize

Multiple Choice

How long does Primary Succession take?

• one year

• hundreds of years

• 20 years

• 40 years

-unlike primary succession, it starts
with soil instead of bare rock

Caused by a catastrophic event (EXCEPT
volcanic eruption)

Turn and Talk: Catastrophic Events

What is a catastrophic event, and what are some

examples?

A catastrophic event is _________. Examples include _______.

(With soil)

(With soil present)

Climax Community: A stable community that has reached
equilibrium

Multiple Choice

Secondary succession starts with

• Lichens and Mosses

• Bare rock

• Soil

• Trees

Multiple Choice

Secondary Succession only happens after

• a volcanic erruption that makes bare rock

• a catastrophic event that exposes soil
