This document defines and provides examples of different types of interspecific and intraspecific relationships between organisms. Interspecific relationships include mutualism, commensalism, inquilism, parasitism, depredation and are either beneficial or detrimental. Intraspecific relationships include gregarious, colonial, social and familial behaviors and are beneficial. Examples are provided for each relationship type.

3. MUTUALISM:
https://www.youtube.com/watch?v=LVRL_MIr7Rs
This is a
relationship
between two or
more individuals
for mutual
benefit.
Example: birds pollinate flowers
Beneficial

4. COMMENSALISM:
https://www.youtube.com/watch?v=RBR_w2-0LiQ
This is a
relationship
between two
living
organisms
where one
benefits, but
the other is
not affected. Example: different race of fish
together
Beneficial

INQUILISM:
Example: a bird with a deer.
This is a
specific form of
commensalism
in which one
organism uses
another
organism for
housing.

PARASITSM:
This is a relationship
in which one species
(a parasite) lives at
the expense of
another species (the
host), and harms the
host in the process.
Example: Fleas in the dog
Detrimental

DEPREDATION:
This is a
relationship in which
one individual (a
predator) kills and
eats another living
being (the prey).
Example: a bear eats a fish
Beneficial

8. GREGARIOUS:
https://www.youtube.com/watch?v=bHpAQLM9Rcw
This describes
groups of
individuals, not
necessarily
related, which
live together for
some time to
provide mutual
help.
Example: migrating birds
Beneficial

9. COLONIAL:
https://www.youtube.com/watch?v=cbN161yBBGA
(0:00 - 0:51)
Related
individuals live
together.
Example: group of corals.
Beneficial

10. SOCIAL:
https://www.youtube.com/watch?v=P4ounedYGKw
This describes groups of
individuals oraganised in
a hierarchy. Work is
distributed within the
group. Individuals usually
have anatomic and
physiological differences. Example: the wolves.
Beneficial

11. FAMILIAL:
https://www.youtube.com/watch?v=phiFrom1nAQ
This describes
groups of
related
individuals
which live
together to
procreate and
protect the
young.
Example: family of lemurs
Beneficial
