Symbiotic Relationships. Symbiosis Symbiosis is a close ecological relationship between the individuals of two (or more) different species.

Population – group of individuals of the same species

Species Relationships

Parasitism… A symbiotic association in which one organism benefits and the other is harmed. Mutualism... A symbiotic relationship in which both organisms.

Interactions Name that Relationship!. Name That Relationship!  Acacia ants live on the bullhorn acacia tree, which provides the ants with food and shelter.

Symbiotic Relationships. What is symbiosis? What it means: Two organisms that live together Temporarily or for a longer time At least one of the organisms.

Symbiosis. Populations that live in close physical contact with each other interact in a variety of ways.

Competition, Predation and Symbiosis. Niche Every organism has a variety of abilities or adaptations that are suited to its specific living conditions.

Community Interactions Community: Many different species interacting in the same environment. Three types of interactions: – Competition – Predation.

Symbiosis Notes

Optional Notes Symbiosis Notes Symbiosis: The relationship in which there is a close and permanent association between organisms of different species. Symbiosis means “living together.” There are 3 main types of symbiotic relationships: Commensalism, Mutualism, and Parasitism.

Optional Notes Symbiosis Notes 1. Commensalism: A symbiotic relationship in which one species benefits and the other species is neither harmed nor benefited. Draw in the faces on your notes.

Commensalism Optional Notes http://upload.wikimedia.org/wikipedia/commons/7/70/Red-breasted_goose_arp.jpg http://redpath-museum.mcgill.ca/Qbp/Images/Birds/peregrine%20falconU.jpg A peregrine falcon and the red-breasted goose breed at the same time and the same place in Russia. The behavior of the falcon protects the nearby geese from predators. The geese benefit from the falcon, but the falcon is neither benefited nor harmed.

Commensalism Optional Notes http://imagecache01a.allposters.com/images/pic/DANPOD/NA02_ANA0020_M~Barnacle-Encrusted-Whale-Tail-Posters.jpg Barnacles live on whales. Barnacles are arthropods that cannot move from place to place. When the whales swim in the ocean, the barnacles get nutritious good from the water. The barnacles do not harm the whales and the whales do not benefit.

Commensalism Optional Notes http://www.airninja.com/pictures/savannah/spanish_moss.jpg Optional Notes Spanish moss and other plants grow on the branches of larger plants. The larger plants are not harmed, but the smaller plants benefit from the additional habitat.

Commensalism

Optional Notes Symbiosis Notes 2. Mutualism: A symbiotic relationship in which both species benefit. Draw in the faces on your notes.

Mutualism Optional Notes http://www.askabba.com/Gazelles%20under%20Acacia%20tree.JPG A type of ant lives on and eats the nectar of the acacia tree. The ants protect the tree by attacking any herbivore that tries to feed on the tree. The ants clear vegetation away from the trunk of the plant and kill any plant that comes too close to the acacia. The tree provides nectar and a home for the ants.

Mutualism Optional Notes http://media.photobucket.com/image/lichen/cottonmanifesto/digital%205/2lichen111506.jpg http://billi-jean.com/images/lj/0607/lichen2.jpg A lichen is a relationship between a fungi and algae. The fungi collect and provide water for both organisms. The algae produce food for both the organisms. Both species of organisms benefit and cannot survive without the other.

Optional Notes Symbiosis Notes 3. Parasitism: A symbiotic relationship in which one organism benefits but the other is harmed. Parasites harm, but usually do not kill the Host. Draw in the faces on your notes.

Parasitism Optional Notes http://www.healthline.com/blogs/outdoor_health/uploaded_images/tick-on-skin-744826.jpg http://dermatology.cdlib.org/DOJvol3num2/fleas/flea8.jpeg Ticks and fleas (parasites) on a dog or cat (host). The ticks and fleas live on and drink blood from the dog or cat. The host is weakened and harmed.

Parasitism Optional Notes http://www.curezone.com/upload/parasites/tapeworm/scolex_tapeworm.jpg http://neatorama.cachefly.net/images/2009-02/tapeworm-rhinebothrium.jpg Parasitic worms live inside the intestines of animals such as dogs, cats, cows, pigs and even humans.
