1. SYMBIOSIS – two or more species live together in a close, long-term association1

2. Parasitism – good for one species, bad for host2

3. Mutualism – both species benefit3

4. Commensalism – one species benefits and the other is unaffected4

5. Symbiosis Activity I’m going to out you in groups of 3
You’re going to create 3 different types of relationships from the organisms on the worksheet
You need an example for each type of symbiotic relationship
Parasitism
Mutualism
Commensalism 5

6. Interspecific Interactions6

7. Competition Species directly competing for resource
-ex. In Africa, lions and hyenas compete for prey 7

8. Predation Predators have ways to find and eat their prey
examples – lions, snakes, spiders, centipedes
Prey have ways to hide from or escape their predators 8
