1. Homeostasis
– the maintenance of a dynamic
equilibrium
– Why does an organism’s internal
environment change?
– Why is a stable internal environment
important to an organism’s survival?
Describe an example.
– Most homeostatic mechanisms
operate as negative feedback loops.
– Draw the components of a basic
negative feedback loop.
p. 7

2. Asexual – single
parent produces
REPRODUCE offspring identical to
parent
Sexual – 2 parents
produce unique
offspring having
characteristics or
traits of each parent

3. Reproduction
Which of these groups of organisms have sexual
reproduction? Which can reproduce asexually?

4. Contain DNA
Deoxyribonucleic Acid
Genetic material
that contains the
“blueprints” for
each organism
Provides directions
for the making of
proteins

5. OBTAIN & USE ENERGY
Required to carry
out life processes-
making and
breaking down
food, movement of
materials and
building of cells
Metabolism – the
sum of all the
chemical processes
in an organism

6. METABOLISM
The Sum of All Biochemical Processes
1. Obtain Nutrition
Sun is the source of
most energy
Producers - Make food
Consumers - Eat
Decomposers – Absorb
2. Digestion – Break down
of large food particles into
smaller pieces

7. 3. Respiration – Mixing food
with oxygen (O2) to release energy
Food + O2 H2O + Waste
Energy
4. Synthesis – Process of putting
together or building up
Making more cells – Growth
Repair of Replace old cells
5. Excretion – removal of wastes
