1. Symbiosis Review/Game! On your sheet, fill in the following symbiotic relationships that you see! Complete the first 3 columns and at the end we will check your responses (4 th column).

2. Fill in the following chart on your sheet right now! Type of SymbiosisOrganism 1Organism 2 Mutualism Predator / Prey Commensalism Parasitism + 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 Competition

3. Check and Review Type of SymbiosisOrganism 1Organism 2 Mutualism++ Predator / Prey++ Commensalism+0 Parasitism+- 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 Competition--

4. 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!
