Definition Repeated interaction between species such that members of a species are killed shortly upon capture by the other species. “Repeated” means that a one time occurrence is NOT predation “killed shortly upon capture” http://scienceblogs.com/deepseanews/mbn_shark_wideweb__470x321,0.jpg Predation? http://dsf.chesco.org/ccparks/lib/c cparks/creaturefeature/deer_brow sing.jpg

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
