SPECIES INTERACTIONS
NOTESStudent Expectation (SE) 12.A – INTERPRET relationships, including predation, parasitism, commensalism, mutualism, and competition among organisms;
I. Competitiona. Organisms compete with each other for
resources - any necessity of life; water, nutrients, light, food, space
b. No two species can occupy the same niche – where an organism lives and what it eats.

Symbiosis Foldable
Copyright Pearson Prentice Hall
Symbiosis – A relationship in which two species live and interact closely together.
II. PredationOne organism eats
another organism and it dies.
Predator: organism that does the killing and eating
Prey: food organism being eaten

III. MutualismBoth species benefit.
“Good for me - Good for you”

Lichen – algae + fungus duo
IV. Commensalismone benefits and the
other is unaffected
“Good for me - Doesn’t bother you”
Copyright Pearson Prentice Hall
V. Parasitism One organism
benefits, the other is harmed.
“Good for me - Hurts you”

SYMBIOSIS PRACTICE
On your whiteboard, write a M for Mutualism C for Commensalism P for parasitism
Hold your board to your chest until asked to show your answer.

Gazelle/OstrichOstriches 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.
Cuckoo/Warbler
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.
Yucca/Yucca Moth
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.
Whales and BarnaclesBarnacles create home sites by attaching themselves to whales. This relationship neither harms nor benefits the whales.
Mistletoe on Spruce Tree
Mistletoe extracts water and nutrients from a spruce tree. The spruce tree is harmed.
Oxpecker/Rhino
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.
Shark/RemoraRemoras 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.
Wrasse Fish/Bass
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.
Cowbird/Bison
As bison walk through grass, insects become active and are seen and eaten by cowbirds. The relationship neither harms nor benefits the bison.
Mouse/Flea
A flea feeds on a mouse’s blood and harms the mouse.
Deer/Tick
Ticks will feed on a deer’s blood and harm the deer.
Hermit Crab and a Shell
Hermit crabs live in shells made and then abandoned by snails. This relationship neither helps nor harms the snails.
Wasp/Catepillar
A wasp lays its eggs on a caterpillar. When the wasp eggs hatch, the larva will eat the caterpillar and kill it.
Bee/Maribou Stork 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.
Honey guide Bird/Badger 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.
Orchids/Bromeliads
Orchids grow inside a bromeliad plant. The orchid obtains water and nutrients from the bromeliad, but does not help or harm it.
Sparrow/Osprey 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.
Heartworms/Dog’s Heart
Heartworms develop inside a dog’s heart. The worms cause health problems and may result in death.
