WRITE THE BELOW KEY UNDERSTANDINGS IN CJ!!
There is interdependence between organisms and their
environment.
— What are the biotic factors an ecosystem?
— What are some abiotic factors in an ecosystem?
— For what resources may organisms have to compete?
— In what ways do organisms depend on each other?
— How are organisms and their environment
interdependent?
Predator
Animal, such as a lion, that kills
and eats other animals (prey).
Prey
Organism
that is
killed and
eaten by
another
organism
(predator).
Parasite
Organism, such
as a tick, that
feeds on cells,
tissues, or
fluids of
another living
organism (the
host).
Host
Organism that supports a
parasite.
Mutualism
Relationship
between two
species in
which both
species
benefit.
Commensalism
Relationship between species in
which one species is helped and
the other is unaffected.
Biotic
Of, relating to,
or caused by
living things.
Abiotic
Not biotic!
Ecosystem
 The living and non-living components of an
environment.
Competition
 In an ecosystem, occurs when more than
one individual or population tries to make
use of the same limited resource.
Interdependent
Relating to two or more people or
things dependent on each other.
Trait
Feature that an
organism
inherits from
its parents,
such as eye
color, that is
coded for by
DNA.
Artificial Reef
 A human-made underwater structure, typically built
to promote marine life in areas with a generally
featureless bottom.
Pollution
Any change
in the
environment
that is
harmful to
organisms.
Runoff
Water from
rain or snow
that flows
over the
surface of the
ground and
finally into
streams or
lakes.
Drought
A long period of dry weather.
