Symbiotic Relationships Activity
Name:
Procedure:
Use the Symbiosis Information given at the end of the assignment to decide who each organism forms a
symbiotic relationship with. You will need to cut and paste (or write!) the matching organisms and
descriptions into the given chart. Then, identify the type of symbiotic relationship it is by circling the
correct answer.

MATCHING ORGANISMS:
DESCRIPTIONS:
As Species A walks
through grass, insects
become active and are
seen and eaten by
Species B.
Species A alerts and
directs Species B to bee
hives. Species B then
exposes the hives and
feeds on the honey first.
Next Species A eats the
honey.
Species A feeds on the
parasites found on
Species B’s body.
Species A extracts
water and nutrients from
Species B to Species
B’s detriment.
Species A feeds on
Species B’s blood to
Species B’s detriment.
Species A uses its sawlike
bill to cut up the
dead animals it eats. As
a result, the dead animal
carcass is accessible to
Species B for food and
egg laying.
Species A may lay its
eggs in Species B’s
nest. Species A’s young
will displace Species
B’s young, and Species
B will raise Species A’s
young.
Species A lives and
hunt with Species B,
and both have access to
the prey.
Species A is pollinated
by Species B. Species
B lay their eggs in the
flowers where larvae
hatch and eat some of
the developing seeds.
Species A lives in a
specific body part of
Species B that Species
B has abandoned.
Species A creates
home sites by attaching
itself to Species B.
Species A feeds on
Species B’s blood to
Species B’s detriment.
Species A feeds on the
ticks found on Species
B.
Species A attach
themselves to Species
B’s body. They then
travel with Species B
and feed on leftover food
scraps from Species
B’s meal.
Species A and Species
B feed next to each
other. They both watch
for predators and alert
each other to danger.
They each see predators
the other wouldn’t see.
Symbiosis Information

Barnacles create home sites by attaching themselves to whales. This relationship neither harms nor
benefits the whales.

Remoras attach themselves to a shark’s body. They then travel with the shark and feed on the leftover
food scraps from the shark’s meals. The relationship neither harms nor benefits the shark.

The stork uses it saw-like bill to cut up the dead animals it eats. As a result, the dead animal carcass is
accessible to some bees for food and egg laying. The relationship neither harms nor benefits the stork.

Hermit crabs live in shells made and then abandoned by snails. This relationship neither helps nor harms
the snails.

As bison walk through grass, insects become active and are seen and eaten by cowbirds. The relationship
neither harms nor benefits the bison.

Orchids grow inside a bromeliad plant. The orchid obtains water and nutrients from the bromeliad, but
does not help or harm it.

A sparrow will build its nest under the nest of an osprey. The smaller birds get protection because other
predators will not mess with the osprey. The osprey are not helped nor harmed by the sparrow.

Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae
hatch and eat some of the developing seeds. Both species benefit.

Honey guide birds alert and direct badgers to bee hives. The badgers then expose the hives and feed on
the honey first. Next the honey guide birds eat. Both species benefit.

Ostriches and gazelles feed next to each other. They both watch for predators and alert each other to
danger. Because the visual abilities of the two species are different, they can identify threats that the
other animal would not see as readily.

Oxpeckers feed on the ticks found on a rhinoceros. The oxpeckers get a meal and the rhinoceros is
helped by the removal of the ticks.

Wrasse fish feed on the parasites found on the black sea bass’s body. The wrasse fish get a meal and the
black sea bass is helped by the removal of the parasites.

Mistletoe extracts water and nutrients from a spruce tree. The spruce tree is harmed.

A cuckoo may lay its eggs in a warbler’s nest. The cuckoo’s young will knock the warbler’s eggs out of a
nest and the warbler will raise the cuckoo’s young.

A flea feeds on a mouse’s blood and harms the mouse.

Ticks will feed on a deer’s blood and harm the deer.

Heartworms develop inside a dog’s heart. The worms cause health problems and may result in death.
 A wasp lays its eggs on a caterpillar. When the wasp eggs hatch, the larva will eat the caterpillar and
kill it.
