– Now get on the computer and go to google
classroom or my.ccsd.net and look for the
student survey assignment. Do it instead of
writing out an in.

1. Write the topic for the
unit in the middle of the
paper and box it in.
2. Divide the paper into 3
equal sections.
3. Put a subtopic/key
word in each section.
4. Add an appropriate
picture to each section(no
stick figures).
5. Each section must
have 3 different
colors(black and white
don’t count). Don’t use
the same 3 colors for 2
different sections.
Use Ch 5 in the textbook

Title - Communities
Cornell Notes Pg. 59
What is a community?
What are Community Interactions
• Predation(+-)
– One organism
kills and eats
another
organism.
What is competition?
• Competition(--)
– 2 organisms are
competing for the
same resource.
– May be interspecific
(between members
of different species)
or intraspecific
(between members
of the same species).
What are Niche and Habitat?
• Habitat-place where an
organism lives.
• Niche-role and position a
species has in its
environment.
– Organisms with the same
niche compete if they are in
the same habitat.
How do Stability & Disturbance work
together?
• Disturbance-events that change a community
by removing organisms or changing resource
availability.
• Stability is the ability of a community to resist
disturbance and not change.
What is Biodiversity?
• The variety of life in an area.
• Measured by species richness-the number of
different species in an ecosystem.
• Extinction is when the last individual of a species
disappears.
– Endangered species=species that are likely to become
extinct.
– Threatened species=species that are close to
becoming endangered.
• Biodiversity increases the stability of a
community
Which has more species diversity?

• It is often said that a habitat is the organisms
“address” and its niche is like its “job”.
Please explain this in 3+ sentences.

• What is a hypothesis?
• What is the independent variable?
• What is the dependent variable?
• Paramecium are microscopic, unicellular protists that live
in water.
• The 2 species we are looking at do not eat each other, it
isn’t a predator prey relationship.
• They compete for the same food. Paramecium are
predators that feed on algae and bacteria

Thinking About This:
• What kind of growth pattern do both species
of Paramecium follow?
**We expect a somewhat slow start and then
a very rapid increase in number.

• What was your hypothesis for the
paramecium lab?
• What was the independent variable for the
paramecium lab?
• What was the dependent variable for the
paramecium lab?

In the virtual lab,
1. What were the paramecium competing for?
2. Was this inter or intraspecific competition?
Why?
