Eco Relationships “Instas”
• Divide your paper to create 4
boxes.
• In each box, draw an “insta”
for each type of ecological
relationship (Think about how
Instagram works…the picture
should describe the
relationships)
• Predation, Mutualism,
Commensalism, and Parasitism
• Include a caption that also
describes the relationship
Essential Question
PG 131
How do ecosystems develop and
change over time?
Standard
B.11D - Describe how events and processes that occur
during ecological succession can change populations
and species diversity.
Think – Pair – Share
What kinds of things do people do to cause
changes in their environment?
What kinds of things happen naturally to cause
changes in the environment?
What is succession?
Succession is when one thing follows
another in a particular sequence.
Ecological succession: when
ecosystems go through a series of
predictable changes after a
disturbance
Mount
Saint
Helens
The series of predictable changes that occurs in
a community over time is called ecological
succession.
Succession that
occurs on
surfaces where
no soil exists is
called primary
succession.
Primary = First = 1 = Back to
Square 1
Two geological events that could lead to
primary succession are volcanic eruptions and
the melting of glaciers.
The first species to populate a new area are
called pioneer species.
Pioneer species prepare an ecosystem for new
species by helping to form soil in which plants
can grow.
Secondary succession follows when a
disturbance of some kind changes an existing
community without removing the soil.
Secondary succession might be caused by
wildfires, hurricanes, or tornados.
Succession affects organism populations in two
ways:
DENSITY:
• The total number of organisms
living in a particular area
DIVERSITY:
• The number of different
species living in a particular
area (also called biodiversity)
• more diverse ecosystems are
healthier
As succession proceeds, both density and
BIOdiversity will increase.
A climax community is a mature, stable
community that does not undergo further
succession.
Plant and animal life returns to an area in a predictable order
after a natural disaster:
1. FIRST (primary succession):
a) pioneer species (lichens) grow on the exposed rock
b) no animal life exists
2. SECOND (secondary succession):
a) small plants like grasses replace pioneer species as soil begins to develop
b) small plant-eating animals return to the area
3. THIRD (secondary succession):
a) medium-sized plants like shrubs return as the soil becomes richer
b) larger plant-eaters and small meat-eaters return
4. FOURTH (secondary succession):
a) large plants like trees return as the soil become nutrient-rich
b) large meat-eating animals return
