SYMBIOSIS – two or more
species live together in a
close, long-term association
•Parasitism –
good for one species, bad for
host
•Mutualism – both species benefit
Commensalism – one species
benefits and the other is
unaffected
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
Interspecific Interactions
Competition
• Species directly competing for resource
-ex. In Africa, lions and hyenas
compete for prey
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
