Symbiosis Notes

•Use the following slides to fill in your symbiosis boxes.

•You are writing everything in blue (definition and any example listed) in the top box, AND drawing the smiley faces in the bottom box.

•The symbiosis definition goes at the top beside the word symbiosis.

Symbiosis

a close, long-term relationship between

two organisms

Mutualism

A symbiotic relationship in which both organisms

benefit

MutualismExample: bird & crocodile

Commensalism

one organism benefits and the other is

unaffected

Commensalism

Example: bird’s nest in a tree

Parasitismone organism benefits while

the other is harmedParasite = the organism that is

benefittedHost = the organism that is

harmed

Parasitism

Example: tick on animal/person

Predation

An interaction in which one organism kills another for food or nutrients

Predator = receiving nutrients/food by killing and consuming prey

Prey = organism that is killed by predator for nutrients/food

Predation

Example: lion hunting and

consuming zebra

CompetitionTwo or more individuals trying to use the

same resource

Example: food, water, shelter, space, or sunlight

*Draw what emoji makes you think of competition in the bottom box*

Symbiosis Coloring Activity• Color in the scenario given to match it to one of the following:

mutualism, parasitism, commensalism, or predation. You make a small mark instead of coloring the entire box if you want to to wait to completely color when you check it.

• There are 5 of each.

• Mutualism = red

• Commensalism = blue

• Parasitism = green

• Predation = yellow

• DO NOT MOVE FORWARD UNTIL YOU ARE FINISHED.

Answer Key

Symbiosis Sort

• Use your sort paper and pieces to sort each relationship into commensalism, parasitism, and mutualism.

• DO NOT HIT NEXT UNTIL YOU'VE SORTED!

Help:

• An oxpecker and a plover are both types of birds.

• A sea anemone is similar to a plant under the water that certain fish live in (like Nemo!).

• Mistletoe is a plant.

• Crocodile & plover

• Cleaner shrimp & a fish

Commensalism:

• Bird in a nest in a tree

• Tiger hiding in the grass
