Answer:
leaves more viable offspring than others of its species
Explanation:
Greater fitness is being conferred on an individual organism compared to the other individual member of a species population if that individual does not only just competes favorably for the limited resources available than the rest individuals, but is in fact able to reproduce more rapidly and thereby pass on such favorable traits, which makes them better competitors, to as many of their offspring as possible. Over time, you will find most of the offspring they leave behind more common in the population than the other.
If an individual organism is referred to as having a greater fitness compared to another individual of the same species, what it simply means is that the organism <em>leaves more viable offspring than others of its species</em>.
