Answer:
<em><u>Predation</u></em><em> is an interaction in which one organism kills and eats another. </em>
This is why an organism that kills another is called a predator. Snakes for instance, are predators of rodents.
<em><u>Competition</u></em><em> is an interaction in which two organisms require the same limited resources. </em>
When organisms require the same resources yet these resources are limited, they will have to compete amongst themselves for those resources. This is what gives rise to Natural Selection.
<em><u>Cooperation</u></em><em> is an interaction in which organisms work together to improve their survival.</em>
Sometimes organisms will work together so that they may have better chances are surviving the environment. This is what drives humans to form complex societies.
