trees.

🐇 A community that was destroyed by
a natural catastrophe 10 years ago.

😀 A stable desert ecosystem that has
not experienced a disturbance event in
centuries.

getting taken over by producers.

Primary Succession

Multiple Choice

What is a climax community?

• An abandoned parking lot that is getting taken over by producers

• A stable desert ecosystem that has not experienced a disturbance event in centuries.

• 🐇 A community that was destroyed by a natural catastrophe 10 years ago.

• Only a big forest

What is a climax
community?

😀 A stable desert ecosystem that
has not experienced a disturbance
event in centuries.

Climax communities are the final
stage of succession where an
ecological community has reached
maximum biodiversity and stability.

Class Norms

Standard

SEV2. Obtain, evaluate, and
communicate information to construct
explanations of stability and change in
Earth’s ecosystems.

c. Construct an argument to predict
changes in biomass, biodiversity, and
complexity within ecosystems, in
terms of ecological succession.

Learning Target

⮚I can show that ecological succession

happens in a predictable sequence.

⮚I can understand the role of that pioneer

species play in primary succession.

⮚I can describe the role of secondary

succession.

Primary Succession

There is bare rock thus: no
soil and no community to
rebuild from.

Common from volcanic
eruptions or newly formed
volcanic islands.

Common from newly
exposed glacial melt lands.

How are soils formed?

Lichens

Usually, lichens
begin to grow on
the rock first.
Because lichens
and some mosses
are among the
first organisms to
appear, they are
called pioneer
species.

Starting Primary Succession

Pioneer species secrete acids that help break down rocks. As
pioneer species die, their decaying organic materials mix with
small pieces of rock. This is the first stage of soil development.
Small weedy plants begin to grow in the soil. These organisms
die, adding to the soil. Seeds brought by animals, water, and
wind begin to grow. Eventually, enough soil forms to support
trees and shrubs.

Pioneer Species

What are they? The first plants
on the scene to colonize an
area.

What are their roles in
ecological succession? They
initiate recovery following a
disturbance.

What are their roles in primary
succession if any? They create
soils.

What do you notice about the soil?

Community

Even though we look at
the plant community
the other organisms
that live there are also
changing.

Why would these
organisms change?

Changing Ecosystems

Ecosystems constantly change. A tree
falling in a forest affects the forest
ecosystem. A fire might alter the forest
habitat so much that some species
cannot survive and others can thrive.
The process of one community
replacing another as a result of
changing abiotic and biotic factors is
called ecological succession.

Climax community

●
Khan’s academy wrote:

●
stable climax communities can form in
some cases, this may be uncommon in
many environments. Ecosystems may
experience frequent disturbances that
prevent a community from reaching an
equilibrium state—or knock it quickly out
of this state if it manages to get there.

Succession

What is it?

Is there a common
sequence or
pattern?

Answer these two questions

Ecological Succession: What is the order?

I am still trying to understand Primary succession

Mr. Science round-up

amalgamation tip

Primary succession has
an “r” which is how it has

only rock(no dirt).
Do you understand

better?

Fist to five

I am still trying to understand secondary succession

Mr. Science round-up

amalgamation tip

Secondary succession

has an “S” which is how it

has only soil(dirt).
Do you understand

better?

Fist to five

Ecological Succession: What did you notice about the plants? Was
this sequence easily predictable?

Primary succession is the establishment of a community in an area of
bare rock that does not have topsoil.

🐇 I have finished my experiment or collected

Lesson Summary

●Pioneer species colonize a bare
or disturbed site to start the
process of soil building.

●Primary Succession is a type of
ecological succession that
begins with bare rock.

●As ecosystems progress
through succession stages
biodiversity increases.

●Biodiversity is the variety of life
in the world or in a particular
habitat or ecosystem.

Human Impact
Primary Succession

Examples of disturbances that cause
primary succession include
retreating glaciers, volcanic eruption
and the erosion of sand dunes.
Human activity can also be a cause
of primary succession, such as the
creation of a paved surface. These
types of disturbances leave bare
rock exposed or otherwise
accessible

are those that eats the

secondary consumers (large predators).

These organisms are sometimes

referred to as apex predators as they are
normally at the top of food chains, feeding on
both primary and secondary consumers.
Tertiary consumers can be carnivores or
omnivores.

Energy decreases as it moves

up trophic levels because energy is lost as
metabolic heat when the organisms from
one trophic level are consumed by
organisms from the next level.
