1. Target 8

2.  Symbiosis  Parasitism  Parasite  Host  Commensalism  Mutualism (Just in case you didn’t write them down, they are on pages R71, R79, R80, and R85. Host is not in the textbook. I can also turn back slides.)

3. An interaction between individuals from two species that live closely together.

4. Parasitism Commensalism Mutualism

5.  A relationship between two species in which one species benefits while the species it depends on, its host, is harmed.

6.  Parasites are often microorganisms.  Ex. Tapeworms feed off of nutrients from its host, while the host is deprived of nutrients and gets sick.

7. Isn’t it GROSS? Tapeworm

8.  A relationship between two species in which one species benefits while the other is not affected.

9.  Commensalism is common in oceans.  Ex. Fish swim under jellyfish for protection. Nothing happens to the jellyfish.

10. Aren’t they COLORFUL? Fish Fish

11.  An interaction between two species that benefits both.

12.  Mutualism can be necessary for survival.  Ex. Protozoans (a type of microorganism) break down wood that the termites can’t digest and get a safe place to live.

13. That tree has a serious INFESTATION problem. Termite damage
