Both predation and scavenging are a kind of direct food related
interspecific interactions. But in predation, one organism called
predator, captures and feeds on the other, the prey. The predator is a
free-living organism which catches and kills another species for food.
However, in scavenging, one organism, called scavenger, eats the dead
bodies of other animals which have died naturally or are killed by some
other animals.
