• What is symbiosis?• What are the different kinds

of symbiosis

By the end of this PowerPoint, you should be able to answer…

Journal Set- Up ( 12R-14L)

Headings12R- Commensalism13L-Mutalism13R- Parasitism14L- Predation Under each heading, you will paraphrase the meaning of each symbiotic relationship

What is symbiosis?

What it means: •Two organisms that live together•Temporarily or for a longer time•At least one of the organisms benefits from the relationship

Literal definition: the act of living together

What are the different kinds of symbiosis?

Mutualism ParasitismCommensalismboth

organisms benefit

one organism benefits

one organism benefits

one organism

is unaffecte

d

one organism

is harmed

MUTUALISM

Example: Ostrich and Gazelle

These two animals feed next to each other in the grasslands. Both watch for predators and alert each other to danger. The visual abilities of these two animals are different so they are able to identify threats the other animal would not see.

“Good for you, good for me!

COMMENSALISM• “Good for me, doesn’t

bother you!Example: Hermit Crab and Snail

Remora and Shark

A hermit crab lives in shells that are made and then abandoned by snails. This neither harms nor benefits the snail.

A remora attaches themselves to a shark’s body. They travel with the shark and feed on the left over food from the shark’s meals. This does not hurt or help the shark.

Parasitism• “Good for me, hurts

you!”

Example: Cuckoo and Warbler Deer and Tick

A cuckoo may lay its eggs in a warbler’s nest. The cuckoo’s young will displace the warbler’s young and will be raised by the warbler.

A tick feeds on deer blood to the detriment of the deer.

Predation

A form of symbiotic relationship between two organisms of unlike species in which one of them acts as predator that captures and feeds on the other organism that serves as the prey.

Parasitism: one benefits, one is

harmed

Example 1: Acacia plant with ant galls

Ants lay eggs on

acacia treeAcacia

covers the infected area with

brown flesh (gall)

Mutualism: both benefit

Example 2: Moray Eel with Cleaner Fish

Moray Eel gets a clean mouth Cleaner Fish gets a meal

Commensalism: one benefits, one is unaffected

Example 3: Cattle with cattle

egretsCattle stir up insects

as they eat grass

Egrets hang

around and eat insects

Commensalism: one benefits, one is unaffected

Example 4: Clown fish with anemone

Clown fish gets

protection Anemone is unaffected

Mutualism: both benefit

Example 5: Antelope with Oxbird

Antelope gets rid of

parasites Oxbird gets a meal

Predation: The owl is hunting the mouse

Example 6:Barn Owl Capturing Prey

Parasitism: one benefits, one is

harmed

Example 7: Taenia worm in human eye

Worm infects human blood

streamHuman may go

blind

Instructions

Read the relationship described on each card. Determine what type of relationship this is and record the name of the organisms on the correct page in your journal.

When you have all your cards completed, use glue or tape to post your cards on its page. VERIFY your answers before gluing/taping.

Tuesday 9-10-13- Tomorrow, Meet in the Library!! Objectives:• Interpret relationships, including predation, parasitism, commensalisms, mutualism, and competition among

organisms.• Compare variations and adaptations of organisms in different ecosystems.• Analyze the flow of matter and energy through trophic levels using various models, including food chains, food webs,

and ecological pyramids.• Recognize that long term survival of species is dependent on changing resource bases that are limited.• Describe how environmental change can impact ecosystem stability.
