5. SYMBIOSIS is the interaction between 2 different organisms living together ◦HOST- usually the LARGER of the 2 organisms ◦SYMBIONT- usually the SMALLER member

6. THE THREE SYMBIOTIC RELATIONSHIPS ARE... PARASITISMMUTUALISMCOMMENSALISM EXTRA PRACTICE ACTIVITY GO BACK TO SPECIFIC QUESTION Click on a Picture Below to Learn About the Relationship EXIT

7. PARASITISM Is a relationship where the Symbiont lives in/on the Host The Symbiont (or Parasite) BENEFITS The Host is HARMED (Do not write)For example, the tick in the picture above is a parasite. It benefits by extracting blood from its human host. The human is harmed because it loses blood and can be infected with disease EXIT

8. Is a relationship between the host and a symbiont Both organisms BENEFIT (Do not write)For example, in the photo above, the host flower benefits by being pollinated by the traveling butterfly. The symbiont butterfly benefits from the nectar that it extracts from the flower. Mutualism EXIT

9. COMMENSALISM the symbiont benefits by receiving transportation, housing, and/or nutrition. The host is neither helped nor harmed. (Do not write) For example, in the photo above the symbiont barnacles receive transportation from the host whale. The host whale is neither helped nor harmed by the barnacles. EXIT

10. EXTRA PRACTICE ACTIVITY In the following activity, you will be given a picture scenario. Identify and select the symbiotic relationship (parasitism, mutualism, or commensalism) represented in the picture. EXIT

15. Clownfish are frequently found in the tentacles of sea anemones. Sea anemones capture their prey by paralyzing them with their tentacles. However, the clownfish produces a mucus that prevents the tentacles from harming it. By dwelling amongst the tentacles the clownfish receives a protected home. The clownfish excretes nutritional wastes that the Sea Anemone can use. This relationship is an example of … PARASITISMMUTUALISMCOMMENSALISM HELPEXIT
