  1. Species Interact In Biological Communities By: Jennifer and Gabe

  2. Compititon Between Species • interspecific competition: the competiton between species for food and other resources.  • Compeition Exclusion: one species succeeding over another when the growth of both species is limited by the same resource • members of a population compete for a limited amount of resources.

  3. Causes: Limited amount of resources   2.Limited amount of (any food such as grass) Results: Alot more competition or animals move/migrate.   2. It puts the organisms out of balance because the animals that eats grass dies then the animal that eats the insect that died, dies Causes and Results of Inspecific Competition

  4. Pictures and a Graph Showing Interspecific Competition

  5. Article On Interspecific Population Rabbits that were put on Austrialia: • Ate all of the grass • Since they have no natural predator there, they are becoming over populated • This also shows interspecific competition http://en.wikipedia.org/wiki/Rabbits_in_Australia

  6. Predator: Keep competing populations down Some also havecolors that camoflague them so they can't be seen Some have acute sense that help them find prey Prey: Use camoflague, warning coloring, and mimicry Others also retreat into safe locations Other things (such as plants) have poisonous chemicals Adaptions of Predator and Prey

  7. What is a Symbiotic relationship?     A Symbiotic relationship is a close ecological relationship between two or more different species.

  8. Types of symbiotic relationship Symbiotic Relationship Terms:           -Mutualism:Both species benefit.           -Commensalism: One species benefits and the other is unaffected.           -Parasitism: One is benefited and the other is harmed.             -Competition: Neither species benefits.             -Neutralism: Both species are unaffected

  9. The Clownfish and the Anemone show Mutualism These two speceies have a Mutually Benefical symbiotic relationship. Clownfish have a protective skin thus they aren't harmed by the anemone.

  10. Barnacles living on whales shows Commensalism      -Barnacles are arthropods.  The whale acts as a rocky surface for the Barnacle to fix itself to.        -The Barnacle gains acces to Nutrient-rich waters.  The whale is not harmed.   

  11. Parasitism Also called a parasitic relationship; one benefits and the other is harmed.  A parasite is what harms the host.         They can be inside or on the surface of the host. Paracites rely on the host to survuve. Koi Paracite- Feed on the Japenese Koi Fish.  They attach to the outter layer of skin. 

  12. Neutralism Meaning two organisims interact but neither are affected. True neutralism is very rare or nonexistent.   It's usually found in situations that are remote or unimportant. The Tarantula and the cactus in deserts is an example.
