Feeding Relationships and Symbiosis

State Standards

• 6th – Life #8 Describe how organisms may interact with one anther

• 7th - Life #2 - Investigate how organisms or populations may interact with one another through symbiotic relationships and how some species have become so adapted to each other that neither could survive without the other (e.g. Predator-prey, parasitism, mutualism and commensalisms)

• 7th - Life 8 Investigate the great diversity among organisms

Learning Objectives

• I will be able to describe and provide examples of the 3 different types of symbiosis.

• I will be able to create a food chain and food web.

Symbiosis

• Symbiosis - is a close relationship between two species that benefits at least one of the species

• Three Types; mutualism, commensalism and parasitism

• Symbiosis Song

• 2. Commensalism -• One species

benefits and the other species is neither helped nor harmed

Feeding Relationships

• Predation -• An interaction in

which one organism kills and eats another

• Killer Whale

• Predator - • the organism that

does the killing• Prey - • An organism that is

killed in predation• Croc

in which one organism eats another
