1 Symbiotic Relationships Species interactions

2 What is symbiosis? Long term partnership between members of different species

3 Types of symbiosis Parasitism Mutualism Commensalism Why not predation? Why not competition between two organisms of the same species?

4 Parasitism 1 species benefits, 1 is harmed +1, -1

9 Tapeworm

10 Mutualism Both species benefit +1, +1

11 Cleaner fish

12 Insects and Flowers

13 Aphids and Ants

14 Birds and Livestock

15 Lichens

16 Commensalism One species benefits, the other is unaffected +1, 0
