To take notes:
Organism
• An individual form of life that is capable of
growing, using nutrients, and reproducing (1
member of 1 species)
Example:
cheetah
Population
• All the members of a single species in one
area
Example:
Herd of
Deer
Community
• All of the populations of different species in a
particular area (all of the biotic factors) and their
interactions with each other.
Ex. Tropical
ocean
community
What might be some possible populations that would interact?
Ecosystem
Example:
Coral reef
• A system consisting of all of the interactions
that occur between the abiotic and biotic
factors within an area.
• What might these be in our example?
Biome
• A large geographic area identified by a
particular type of common plant or animal
Temperate
forest
Biosphere
• The portion of Earth that is capable of
supporting life. The biosphere includes the
outer region of the earth (the lithosphere) and
the lower region of the atmosphere.
Habitat
• The place where an organism naturally lives
and grows (it’s home) – it is made within an
ecosystem.
Species
• A group of organisms that look like each other
and are able to breed among themselves with
mates.
Interdependent
• 2 organisms that are
dependent on each
other for survival
• Example: this
butterfly depends on
the flower for nectar
(food) and the flower
depends on the
butterflies for
fertilization.
