Levels of Organization • The smallest level of organization is a
single organism, which belongs to a
population that includes other members
of its species.
Living Things and the Environment
Levels of Organization
• The population belongs to a community
of different species.
Living Things and the Environment
Levels of Organization
• The community and abiotic factors
together form an ecosystem.

Adapting to the Environment
• Every organism has a
variety of adaptations that
are suited to its specific
living conditions.
Interactions Among Living Things
Predator - Prey Interactions • On Isle Royale, an
island in Lake
Superior, the
populations of
wolves (the
predator) and moose
(the prey) rise and
fall in cycles.
Interactions Among Living Things
Predator - Prey Interactions
–Year; numbers of
wolves and moose
• Reading Graphs:
– What variable is
plotted on the x-axis?
What two variables
are plotted on the y-
axis?
Interactions Among Living Things
Predator - Prey Interactions
–The moose population
increased and then
decreased; the wolf
population increased.
• Interpreting Data: – How did the moose
population change between 1965 and 1972? What happened to the wolf population from 1973 through 1976?
Interactions Among Living Things
Predator - Prey Interactions
–As the moose
population increased,
more food was available
to the wolf population and
it increased.
• Inferring:
– How might the change in the moose population have led to the change in the wolf population?
Interactions Among Living Things
Predator - Prey Interactions
–The wolf population increased.
• Drawing Conclusions:
– What is one likely cause of the dip in the moose population between 1974 and 1981?
Interactions Among Living Things
Predator - Prey Interactions
–Disease would cause a decrease in the wolf population, so fewer moose would be eaten and the population could increase.
• Predicting:
– How might a disease in the wolf population one year affect the moose population the next year?

What You Know
What You Learned
Review
1. Organisms interact in different ways.
1. Organisms are adapted to their environments. 2. Organisms have niches, which are their roles in their habitats. 3. Organisms compete for resources. Some organisms eat
others, and this affects the size of populations. 4. Some organisms live together in symbiotic relationships, of
which there is mutualism (both benefit), commensalism (one benefits, the other is not helped or harmed), and parasitism (one benefits, the other is harmed).

There are four main ways to determine the size of a population.

Count signs

Changes in Population Size
• Populations can
change in size
when new
members join
the population or
when members
leave the
population.
Studying Populations
Question Answer
How do you determine
population size?
Some methods of determining population
size are direct observation, indirect
observation, sampling, and mark-and-
recapture studies.
What causes populations to
change in size?
Some factors include birth, death,
immigration, and emigration.
What are limiting factors? These are factors that can limit population
growth if they are unfavorable for the
organisms in the population. Food and
water, space, and weather conditions can
be limiting factors.
