Ecology Review
Terms
Goal: Review the following
terms for a vocabulary
assessment on Friday.
Ecosystem

Definition: the
community of
organisms that live in
a particular area,
along with their
nonliving
surroundings

Example: Lake in
New England
Habitat
 Definition:
an
environment that
provides the things
an organism needs
to live, grow, and
reproduce
 Example: Butterfly
Garden
Biotic Factor
 Definition:
A living
part of an
organism’s habitat
 Example: Turtle,
plant, snail shell
Abiotic Factor
 Defintion:
a
nonliving part of an
organism’s habitat
 Example: Air,water,
the sun
Population
 Kid
Friendly
Definition: all the
members of one
species in a
particular area
 Example: Humans
on a beach
Organism
 Kid
Friendly
Definition: A living
thing
 Example: Cougar
Interdependent
 Kid
Friendly
Definition: relying or
depending on
each other
 Example: bee
needs the flower
for nectar and the
flower needs to
bee for cross
pollination
Environmental Features
 Kid
Friendly
Definition: Parts of
an environment
that help an
organism survive
 Example: glaciers
Community
 Kid
Friendly
Definition: all the
different
populations that
live together in an
area
 Example: different
organisms living in
the same
ecosystem
How do living organisms use
their environment to survive?
 Answer:
They use
the environment
for food, water,
and shelter.
 Example:
giraffe
drinking water

pond, river, etc.
 *rocky sea scape
 *sand dunes
How do abiotic features help
support life?


Answer:
Water (organisms use to
drink and provide a
habitat)
*Sunlight (plants use for
photosynthesis)
*Oxygen (organisms use
to breathe)
*Temperature (cold
blooded organisms use
to heat their body)
*Soil (plants use to gain
nutrients)
How are Biotic Factors and
Abiotic Factors
interdependent?

Answer:
water - animals drink it or live in it /
animals take the water into their
bodies and release it in a different
location, so they help to move
water
*sunlight - plants need it for
photosynthesis / plants take the
sun's energy and change it into a
form of energy that is usable by
animals
*oxygen - organisms use it to
breathe / animals breathe out
carbon dioxide which is a necessary
ingredient for photosynthesis so the
plant can make more oxygen
*soil - animals use soil for their
homes / animals add nutrients to
the soil and help mix the nutrients
into the soil
