STAAR Review
Category 4
Students demonstrate an understanding of the
structures and functions of living organisms
and their interdependence on each other and
their environment.

Organisms
Populations
What's the Function?
• Circulatory
– Transport food & oxygen to cells
– Transport waste products from cells
• Respiratory
– Provide oxygen to the blood
– Remove carbon dioxide from the blood
• Skeletal
– Support, protection, and movement
7.12B
What's the Function?
• muscular
– Body Movement
– Movement of blood and food
• digestive
– Break down food to nutrients
– Deliver nutrients to circulatory system
• excretory
– Remove wastes from the body including
excess water
7.12B
What's the Function?
• reproductive
– Pass genetic information to offspring
– Continue the species
• integumentary (skin)
– Protection
– Reduce water loss
• nervous
– Process information & send instructions
7.12B
What's the Function?
• endocrine
– control homeostasis
– regulate bodily functions like
metabolism
– control growth
– Control development
– reproduction
7.12B
Reproduction
• Inherited traits controlled by _1?_.
– Found in _2?_, located on _3?_ found
within the _4?_ of a cell.
• Asexual vs. sexual
– Which creates more diversity?
Photosynthesis…

Energy Flow through
Living organisms..
• Sun  producers  primary consumers
 secondary consumers
• Food chains
• Food webs…
• decomposers

Texas Food Web
Which of these are
producers?
Which of these are
primary
consumers?
Which of these are
secondary
consumers?
Which of these
are tertiary
consumers?

Question
• Which organisms are both secondary
and tertiary consumers in this partial
desert food web?

Question
• Flowers in a vase have enough turgor
pressure to look fresh. If they lose turgor
pressure, they become wilted. How is
turgor pressure maintained?
A. air is pumped into flowers
B. water moves into cells
C. minerals turn to crystals
D. more sugar is produced
E. water is pumped out of the cells
F. more sugar is consumed

Ecosystem Factors
• Biotic
– Living
• Plants
• Animals
• Decomposers
8.11B
• Abiotic
– Non-living
• Water
• Soil
• Rocks
• Air
• Light
Discussion
• Given two organism that
consume the same things
in aa forest ecosystem,
what would happen to
the organisms if a
drought caused a major
loss of trees?
8.11C
Succession
• What is it?
– series of predictable changes in a community that
occur over time
– Begins on new land such as a volcanic island
– After major event: volcanic eruption, fire
• 2 types
– Primary: start with no ecosystem existing; 1st—
pioneer species (lichens & mosses) then grasses,
shrubs and finally trees
– Secondary: occur after a disturbance such as
farming or logging; regrowth of grasses, shrubs,
small then larger trees

Organism Structures
A dichotomous key
to these six species
is shown. Complete
the missing
information for
sections 5.a. and
5.b. so that the key
is complete for all
six species.
7.11A
Organism
Structures
Using the
dichotomous key,
classify an
organism that has
small or no wings,
shorter rear legs,
not a horned head
and small eyes.
7.11A
Explain the Relationships
• Producer — Consumer
• Predator — Prey
• Parasite — Host
8.11A
Organisms &
Environmental Change
• Polar bears are dependent on sea ice
to hunt seals and to move from one
area to another.
• What might happen to the polar
bears if global climate change
continues?
8.11C
Differentiate between
Natural Selection &
Selective Breeding
• Both are ways traits are passed from parent to
offspring
• Natural Selection
– Referred to “survival of the fittest”
– Only the most adapted organisms live to pass on their
genes
– Peppered moth and air pollution
• Selective Breeding
– Human controlled
– We physically breed for the traits we WANT in the
offspring
– dairy cows
