  2. 17. Symbiosis- • A relationship in which two species exist together and at least one of the species benefits from the interaction • There are three types of symbiotic relationships: mutualism, commensalism and parasitism

  3. TREE MAP OF SYMBIOTIC RELATIONSHIPS:

  4. 18. MUTUALISM- • A relationship between organisms in which both species benefit from the interaction • Occurs in animals of different species • Key words: both benefit

  5. EXAMPLE OF MUTUALISM: • A sea anemone and a clown fish • The sea anemone benefits because the clown fish attracts other fish and the clown fish benefits because it gets protection

  6. 19. COMMENSALISM- • A relationship between organisms in which one species benefits and the other species neither benefits nor is harmed by the interaction • Key words: one benefits, one unaffected

  7. EXAMPLE OF COMMENSALISM: • A shark and a remora • The remora benefits because it gets pieces of leftover food and the shark is unaffected

  8. 20. PARASITISM- • A relationship between organisms in which one species benefits and the other is harmed by the interaction • Key words: one benefits, one is harmed

  9. MORE EXAMPLES OF PARASITISM: • A human with lice • The lice benefits because it gets food and a place to live on the human. The human is harmed • A cat and roundworm is another example. Who benefits? Who’s harmed?

  10. 21. PARASITE- • An organism that lives off the energy of other living things • The “bad guy” in parasitism • The flea is a parasite

  11. MORE EXAMPLES OF A PARASITE: • The roundworm is a parasite in the example of a cat and a roundworm • Lice is the parasite in the human and lice example of parasitism

  12. 22. HOST- • An organism that a parasite lives in or gets nourishment from • The “good guy” in the examples of parasitism

  13. EXAMPLES OF HOSTS: • The human in the human and lice example • The cat in the cat and roundworm example

  14. Ring worm on a human
