is the scientific study of the interactions between
organisms and their environment
is the part of the Earth, including air, land, surface
rocks, and water, within which life occurs
is a natural unit consisting of all Biotic (living factors)
in an area functioning together with all of the
Abiotic (non-living physical factors)
Abiotic vs Biotic
Why???
MAKE ENERGY (cellular respiration)
is a group of interacting organisms
sharing an environment
is the collection of interbreeding organisms of a
particular species
Organisms that use the sun directly are
referred to as producers
Examples: plants, trees, grass
Organisms that feed on the producers for
their energy are referred to as
____________________________
Examples: cow,
insects, deer,
mushrooms
PLANT EATERS
Organisms that feed on the primary
consumers for their energy are referred to as
___________________________
Examples: penguins,
tigers, birds
ANIMAL/Meat EATERS
Organisms that feed on the secondary
consumers for their energy are referred to as
_____________________________
Examples: fox,
hawk, tigers, frog,
human
ANIMAL & PLANT
EATERS
Organisms that feed on dead organic matter
and recycle nutrients back to the land are
referred to as

Examples: Bacteria
and fungi
FOOD CHAIN
Displays the feeding
relationships between
species within an
ecosystem
Shows the flow of
energy from one
organism to the next
and to the next and to
the next
Display many
interconnected food
chains because in most
natural settings
consumers are not
limited to one source
of food
Practice
Grass
They eat grass and crickets
is a graphical
representation designed
to show the biomass or
productivity at each
trophic level in a given
ecosystem
Biomass is a measure of the animal and plant life
that is found in a given area
As you move UP the pyramid:
•The biomass decreases with
each level
•The amount of energy
decreases with each level
•The organisms become more
complex with each level
Omnivore
Carnivore
Herbivore
Producer
Herbivore
commonly describes the
close and often longterm
relationships/interactions
between different
biological species
any relationship
between individuals of
different species
where both individuals
derive a benefit
,
An example would be a
honey bee and a dandelion.
The honey bee gets to eat
the pollen from the flower.
The dandelion uses the bee
to spread its pollen to
another flower.
Coral reefs are the
result of mutualisms
between coral
organisms and various
types of algae that live
inside them
goby fish lives together with shrimp
The shrimp digs and cleans up a burrow in the sand
in which both the shrimp and the goby fish live.
The shrimp is almost blind leaving it vulnerable to
predators when above ground. In case of danger
the goby fish touches the shrimp with its tail to
warn it. When that happens both the shrimp and
goby fish quickly retract into the burrow
a relationship
between two living
organisms where
one benefits and
the other is not
significantly
harmed or helped.

Clown Fish and Sea Anenome
A relationship is
one in which one
member of the
association benefits
while the other is
harmed
almost all free-living
animals are host to one
or more parasite
