DO NOWDate:3/23
-Make a pile in the aisle with your old DO NOW sheet.-Make a separate pile with ‘last’ week’s homework if you haven’t turned it in.-Put this week’s homework away.
What are three abiotic parts of an ecosystem?
ESSENTIAL QUESTION:How do ecosystems change over time?
OBJECTIVES:-Identify Abiotic and Biotic Factors in an ecosystem-Discuss their importance-Observe how the succession plot has changed over time
Succession Plot
- Go outside and examine succession plot from two weeks before
- Make observations along with predictions for another week
- Note any new growth on the plot along with comparisons to the undisturbed ground around it
Outside Expecatations
• -Voice Level 0 in the hallway• -Voice Level of 1 or 2 outside while you
examine the succession plot• -Classes are very near the plot, so be mindful
of your volume!• Stay in one spot in close vicinity to the plot
where you can see and draw• Do not wander!

Predictions: What will you observe a week from now?

KEY:Primary Succession Secondary Succession
ENGAGE: Word Sort
Sort the cards at your table into two groups:
Living (BIOTIC) Non-living (ABIOTIC)
Turn and Talk
With a partner, discuss what you think is the difference between a Biome and an Ecosystem

BIOME Regions of earth that share similar climate, soil, vegetation, and animals.
(Fill in some examples of Biomes we learned about before Spring Break)

How do fires change an ecosystem? Can they be good for a habitat? Why or why not?
ESSENTIAL QUESTION:How do ecosystems change over time?
OBJECTIVES:-Identify Primary and Secondary Succession-Examine stages of succession after the eruption of Mt. St. Helens
Turn and Talk
• Turn and talk with your partner to discuss:
What are some examples of events that can cause an ecological community to be completely destroyed?

Secondary Succession
Pioneer species + other species begin to grow
Secondary Succession
A new community of organisms is being established
Secondary Succession
New climax community is established
Bare rock is exposed due to some type of
disturbance like a retreating glacier or
volcanic eruption. No soil is present.
Pioneer species, like lichens and mosses, establish themselves
on the rock substrate.
Pioneer species die and decay, providing soil and nutrients for
other plant species like shrubs and small trees.
Small and Large trees begin to grow, and the community reaches an
equilibrium or balance. This results in a climax community.
Primary Succession: The establishment of new community where none existed before.
Pioneer Species:
Lichens
Moss
Climax Community• Stable, end stage of ecological succession in which
organisms use resources efficiently and balance is maintained.
Secondary Succession: The reestablishment of community following disturbance.
Organisms are driven away or killed by some
type of disturbance, like a forest fire,
leaving behind only the soil.
Pioneer species, like grasses and weeds,
begin to grow from the soil. Roots and seeds
left over may also begin to grow again.
Some pioneers species die and are replace or outcompeted by other species like shrubs and
small trees.
Small and Large trees begin to grow, and the community reaches an
equilibrium or balance. This results in a climax community.
Habitat Vocabulary pg 49Primary Succession- when an area regrows after
a disturbance has removed all plants and SOIL Secondary Succession- when an area re-grows
itself after a disturbance has removed all plants and the soil still remains
Pioneer Species- the first species to start growing in an area
Climax Community- when an area has grown into a stable community
Climax Community• Stable, end stage of ecological succession in which
organisms use resources efficiently and balance is maintained.
