What are some ways that organisms closely interact with each other, other than

eating each other or competing for resources?

Each group will be given a stack of cards with organisms that interact with each other

Your Task:Pair the organism that interact with each

otherGroup the Pairs together based on similar

relationships: +/+ +/0 +/-

Have me check your work!

Get into your groups!

SYMBIOSIS!A close, prolonged relationship between two or more different

organisms of different species where at least one organism benefits

There Are Three Types Parasitism

Commensalism

Mutualism

Commensalism One organism benefits and another is

unaffected +/0 Example: Hermit Crabs using shells from

other organisms Its like: A race car drafting

Mutualism both organisms involved benefit from the

relationship +/+ Example: NEMO! Marlin lives in an

anemone which provides protection for him, and he eats the algae and excretes waste that the Anemone can use

Its like: Working together as a team!

Parasitism One organism benefits at the expense of

the other (one suffers) +/- Example: Leeches attach to other

animals to suck out blood to feed on Its Like: A thief and their victim

Ticket Out! On a piece of paper to be handed in before you leave

write what type of symbiotic relationship is being described: The remora is a fish that in this picture is attached

to a sea turtle. It gets a free ride from the turtle and feeds on the scraps of food it leaves behind

Organisms interact in other ways besides eating each other. These symbiotic relationships play an important role in ecosystems.
