What are some ways that organisms closely interact with each other, other than eating each other or competing for resources?
Get into your groups! • 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 other • Group the Pairs together based on similar relationships: • +/+ +/0 +/- • Have me check your work!
PAGE 8 of your packets! 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: • Theremora 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
Symbiosis a close relationship between two organisms of different species that benefits atleast one of them Mutualism Commensalism Parasitism +/0 +/- +/+ Hermit Crabs and other organisms Shells Clown Fish and Anemones Leech and host Working together on a project A thief and a victim A drafting car Organisms interact in other ways besides eating each other. These symbiotic relationships play an important role in ecosystems.
