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 relationship0 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!
Which am I?
Acacia ants from Africa feed off sugar deposits on the Acacia tree and defend it from other insects.
