2.  5 different kinds of symbiotic relationships
between organisms
◦ Mutualism
◦ Commensalism
◦ Parasitism/Predation
◦ Competition
◦ Neutralism

3.  The relationship between two different
species of organisms that benefit from each
other.
◦ Ex. Anemone fish and sea anemones.
 Sea anemones hides and protects the fish from
predators with its stinging tentacles.
 Anemone fish defend sea anemones from predators
such as the butterflyfish.

4.  One species benefits while the other species
is unaffected.
◦ Ex. A bird living in a tree
 The bird benefits by having a home.
 Tree has no benefit.

5.  One species of organisms benefits while the
other is harmed.
◦ Tapeworm inside of a human.
 Tapeworm benefits by receiving nutrients from the
host human.
 Human is harmed in the process.
◦ Lion hunting a rabbit.
 Lion benefits from eating the rabbit for nutrients.
 Rabbit dies.

6.  This relationship harms both species of
organisms. Organisms compete for the same
resources.
◦ Ex. An eagle and a hawk
 Both species compete when hunting for prey.

7.  When species are unaffected by their
relationship with one another.
◦ Ex. A tarantula and a cactus
 Tarantula and cactus do not affect each other in any
way.
