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!

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

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.
