    2. 2. Prey-Predator 1) Its an interaction 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. 2) In ecology, predation is a mechanism of population control. Thus, when the number of predators is scarce the number of preys should rise. When this happens the predators would be able to reproduce more and possibly change their hunting habits. As the number of predators rises, the number of preys decline. This results in food scarcity for predators that can eventually lead to the death of many predators. http://upload.wikimedia.org/wikipedia/commons/ thumb/6/61/MNP_Python_at_Moyer.jpg/220px- MNP_Python_at_Moyer.jpg Indian Python swallowing a full http://upload.wikimedia.org/wikipedia/commons/thumb/3/30/ Male_Lion_and_Cub_Chitwa_South_Africa_Luca_Galuzzi_2004.JPG/220px- Male_Lion_and_Cub_Chitwa_South_Africa_Luca_Galuzzi_2004.JPG grown Chital Deer at MudumalaiLion and cub eating a Cape Buffalo National Park
    3. 3. Mutualismrelationship between twospecies of organisms thatbenefits both speciesExample: Bee collecting pollenBees and Sunflowers http://www.picable.com/Nature/Insects/Close-up-of-Bee-Collecting-Pollen.884123Bees get honey for foodSunflower gets itself pollinatedor pollen gets pollinated toother plants Butterfly collecting pollen http://blogs.answersingenesis.org/blogs/creation-museum/2006/11/24/little-blessings/ http://www.nearctica.com/ecology/pops/mutual.htm#pollinate
    4. 4. CommensalismCommensalism is a relationship between 2 animals where 1 organism benefits while the other isneutral (no harm done nor any benefit is gained).http://en.wikipedia.org/wiki/Commensalismhttp://www.bio.miami.edu/dana/pix/cattle_egret.jpg http://sanctuaries.noaa.gov/pgallery/pgfarallones/living/barnacles_300.jpg The Barnacles live on whales andThe birds are looking out for insects get transported to different that are stirred up by the cattle. areas with the whale.

    5. 5. Parasitism• Relationship where 1 organism (Parasite) benefits at the expense of another organism (host) Example:• Cymothoa exigua , a Tongue-eating louse• Parasite of the spotted-rose snapper The little bugger• (n.d).

    6. 6. Symbiotic relationships among plants Commensalism: Creeper plants (Epiphytes) climb up a tree to reach the canopy for sunlight Boston Ivy ‘climbing’ on a wall A creeper plant climbing up onto a sturdy tree to reach sunlight. http://www.plantcare.com/encyclopedia/boston-ivy-745.aspx http://www.jungleschool.com.my/educamps.htmlhttp://users.rcn.com/jkimball.ma.ultranet/BiologyPages/S/Symbiosis.html#Epiphytes
