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 same way – 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!
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 four symbiotic relationships they
represent!
• Keep in mind competition is also between
species (or within the same species) who are
competing for the same resources (food, habitat
and niche.) They can also be a type of symbiosis.
• Keep a running tally and we’ll share our thoughts
and debate at the end! Good luck!
