a forest fire California or Georgia?

5
Vocabulary terms(standard essential)
Catastrophe: a significant and sudden event that causes widespread destruction or disruption,
often leading to ecological changes and initiating the process of succession.
Intermediate Species: species that appear during the stages of ecological succession, often
filling the gaps between pioneer species and climax communities, contributing to the overall
biodiversity of the ecosystem.
• Disturbances can be minor or major, and can affect the ecological community, as well as
non-living features like soil and water.
•
6
Vocabulary terms(standard essential)
• secondary Succession: the process of ecological change that occurs in an
environment that has a temporary change which has soil remaining.
• Climax Community: a stable and mature ecological community that has
reached a final stage of succession, characterized by a diverse range of
species and a balanced ecosystem.
•
Pioneer Species: the first organisms to colonize previously disrupted or
damaged ecosystems, helping to create conditions that allow other species to
thrive.

How can scientists
determine if an ecosystem
will recover from a
catastrophic natural event?
Today is part two of two days we will
explore how is change in an ecosystem
measured according to events of change.
How do scientists categorize
and identify primary vs secondary succession in an
ecosystem?
11
Ecological succession
the process by which the species and environmental
factors in an area change over time.
Disturbances are events that cause large and rapid
changes to an ecosystem, which can then trigger
succession
12
Change in
ecosystems happen
at different levels.
There are two types
primary and
secondary
succession
occurs when species are
colonizing a new habitat that
was previously devoid of life.
An example of primary
succession is the formation
of an ecological community
atop newly formed igneous
rocks after a volcanic
eruption. Because the rocks
just formed, the community
is forming on them for the
first time (hence, primary
succession).
happens after a
disturbance that caused
a sudden change in an
existing ecosystem,
such as a wildfire or
flood. Such
disturbances may
(temporarily) wipe out
or scare off many of the
species living there
before the disturbance.
Primary succession Secondary
succession
13
Disturbance
• A change in an
ecosystem is
caused by a
disturbance.
• A succession does not
start until post
disturbance(after the
catastrophe)
Lets go over the parts of change in
secondary succession
14
secondary succession
• secondary succession starting with soil, next is pioneer
species, intermediate species small shrubs, pine trees and
hardwood trees
15
The first organisms to arrive after a
catastrophe that has destroyed an
ecosystem is complex grass and small
vegetation.
You ever wonder what is left from a wildfire?
Pioneer species
are
intermediate species
16
• Intermediate plant species include grasses, shrubs, and some trees that can survive in thin topsoil.
•
Intermediate species often include shade-intolerant plants which thrive in the relatively open, post-
disturbance landscape.
• As more and more plant species become established, they help create habitats for different animal species
to return to.

18
Climax community
(shade-tolerant)
• Climax (shade tolerant) species: Climax species are the last species to return
to an area following a disturbance. Climax species require a thicker layer of
nutrient-rich topsoil to grow.
• Climax species often include shade-tolerant tree species, which can grow
from seedlings beneath a canopy of shade-intolerant trees, as well as any
animals that rely on these tree species.
19
Wild fires
ires can trigger ecological succession, a process that involves the regeneration of ecosystems after a
disturbance. The type of succession that occurs depends on whether the fire kills all trees and removes
surface organic matter, or if some soil and nutrients remain
20
Humans impact the cycle of disturbance and succession in many ways. People create
unnatural disturbances such as clearcutting forests. Humans sometimes introduce invasive
species that take the place of native species during the succession process. We also alter
the timing of disturbances, causing disturbances to take place more or less often than they
should naturally. Humans often try to prevent disturbances like fires, floods, and
landslides because they damage our buildings, roads, and homes. However, altering
natural disturbance regimes has a history of coming back to haunt us.

Change and ecosystems
Terrestrial and
aquatic biomes all
have balance of
change
Secondary succession
happens in ecosystems
why is it important?
What is the good from
it?
Will the
change
bring life?

CHECK FOR UNDERSTANDING:
23
Biomes
When we talk about succession this is the picture you usually see.
Think about the organisms in different biomes. What do you see as you follow
the arrows?
24
Climax Community
Just like a food web, each
biome has different
organisms so the climax
community will look
different.
An ecosystem is always
developing to its most
complex and stable state.
25
Let’s see how you do?
The wildfire has gone out of control, and
we need to be the ones to put the
ecosystem back together in the proper
order
26

Reorder the following steps for secondary succession

Lesson Summary
➢
A Science Fair project has specific elements
that are required.
➢
I can investigate something that I am
interested in for my Science Fair project.
➢
I can research my idea.
➢
The first law of thermodynamics explains that
energy changes form in an ecosystem but it
doesn’t disappear.
➢
The second law of thermodynamics explains
that most energy in an ecosystem is used to
help the organism survive and is not available
at the next level.
➢
Changing events in an ecosystemto determine
its success.
41
Lesson Summary
➢
Ecological Succession involves a series of changes in
an ecosystem from either starting a new community
or replacing an older community.
➢
An ecosystem is always trying to develop to its most
complex and stable state.
➢
Disturbances from succession events cause a
decrease in biodiversity, biomass, and complexity
within food webs.
➢
As ecosystems progress through succession stages
biodiversity increases.
➢
Biodiversity is the variety of life in the world or in a
particular habitat or ecosystem.
➢
Biomass is the total mass of organisms in a given
area or volume.
