1 symbiosis TN Standard:
symbiosis TN Standard: 6.LS2.2: Determine the impact of competitive, symbiotic, and predatory interactions in an ecosystem.

2 Symbiosis is… Commensalism Parasitism
A close, long-term relationship between two species that usually involves an exchange of food or energy. Mutualism Commensalism Parasitism Which type of relationship do you think is shown in the picture?

3 Mutualism is… A symbiotic relationship between two species in which both organisms benefit.

4 Commensalism is… A relationship between two species in which one organism benefits and the other is unaffected. Remoras Barnacles

5 Parasitism is… A relationship between two species in which one organism (the parasite) benefits and the other organism (the host) is harmed.

6 Parasites….. ew!!!!!!! Now for a little pop quiz…

7 Can you identify these symbiotic relationships ?
1. 2. 3. 4. 5. 6.

8 “Are you talking to me?” Turn to your neighbor and explain The 3 relationships of Symbiosis: Mutualism Commensalism Parasitism
