Note: Remember, Predator / Prey relationships are mutalistic! Predators benefit from having
prey to eat and based upon the evolution and adaptation of the prey, force them to be smarter
and faster. Prey benefit from having predators control their populations from exceeding their
carrying capacity (the maximum amount of a population to be sustained from their
environment) and destroying the entire population.
Competition is the similar – by competing for resources checks the population and ensures
those that reproduce are the most fit (smartest, fastest, best suited to survive) to the
environment. However, this hurts all involved in that particular relationship.
Key:
+ means they benefit from the relationship
0 means nothing, they neither benefit nor harmed from the relationship
- means they are harmed in a negative way from the relationship
Your Turn!
• On the next slides, determine which of the
following five symbiotic relationships they
represent!
• Keep in mind competition is also between
species (intraspecific) or within the same
species (interspecific) who are competing for
the same resources (food, habitat and niche.)
• Keep a running tally and we’ll share our
thoughts and debate at the end! Good luck!
