Example:
Sub adult male
lionandspotted
hyenain the Masai
Mara. The two
species share the
same ecological
niche, and are thus
in competition with
each other.
Example:
Male hartebeest
locking horn and
fiercely defending
their territories.
Example:
A polar bear feeds
on a bearded seal it
has killed. Polar bear
is a predator and
bearded seal is a
prey and energy
flow is from seal to
bear.
Example:
A leech is a parasite
which feeds on
animals blood.
A mature leech may
feed only twice a
year, taking months
to digest a blood
meal.
Example:
A Red billed
oxpecker feed on
ticks of different
cattle or mammals,
so in this relationship
both organism get
benefit from each
other.
Example:
Barnacles attach to
whales or molluscs
shells in order to be
where food is
available. This also
act as transportation
for them and their
safety.
