Competition Predation And Symbiosis
Competition, Predation, and Symbiosis — Graphic Organizer Objective
: To identify the ways that organisms interact with other organisms within their environment. Natural selection is a process through which characteristic that makes an individual better suited to its environment may eventually become common in that species. Adaption is a result of natural selection in the behaviors and physical characteristics that allow organisms to live successfully in their environment. A niche is the role of an organism in its habitat, or how it makes it living. A niche includes the type of food an organism needs, how it obtains its food, and which other organisms use the organisms for food. Three of the major types of interactions among organisms are competition, predation, and symbiosis. II. Relationships — Directions: þ Summarize the characteristics of the relationship. þ Provide a real world example and include an image to represent it.
a. Competition is the struggle between organisms to survive as they attempt to use the same limited resources. Two birds fighting for the same worm is an example of competition. http://ibc.lynxeds.com/photo/wanderingalbatrossdiomedeaexulans/twobirdsfightingoverfoo dwater b. Predation is an interaction in which one organism kills another for food. A coyote kills a squirrel for food to eat is an example of predation.
http://www.vegansouls.com/cruelsports c. Symbiosis is a close relationship between two species that benefits at least one of the species. Mutualism is a relationship in which both species benefit. A bee gets nectar from flowers and a flower gets pollen from a bee. http://lastoneeating.wordpress.com/tag/honeybeeflowermix/ Commensalism is a relationship in which one species benefits and the other species is neither helped nor harmed. A bird takes sap from a tree.
Parasitism involves one organism living on or inside another
