Species Relationships How species get along

For any two different critters, they l Get along well - good buddies! l Don’t really care - apathetic l Go at it - enemies l There are other possibilities

1) Predation l The big, bad PREADATOR l They get to eat the PREY l Usually the prey is not too happy. l When one animal consumes and receives its energy from another living animal.

2) Parasitism l A relationship that is bad for one organism and good for another. l Is it different than PREDATION? l Yes! The other critter is not killed

1 billion people plus on the planet have round worms in the intestines

3) Mutualism l A relationship between species that is beneficial for both. l Birds cleaning out the teeth of alligators l Alligator gets a free flossing l Bird gets a meal

What does the bee get? What does the flower get? What do these two critters get out of the relationship?

4) Commensalism l A relationship between species that is helpful for one. l The other species is neither helped nor harmed.

Another example l See the shrimp on top? l Who benefits - the shrimp or the slug? l How? l Is the other one hurt?

Another example l The tiger kills the prey. l He/she eats. l The vulture gets to clean up afterward. l Does not affect the lion one way or the other.

Another Factor: Competition l Organisms competing for a LIMITED RESOURCE l Like food l water l space
