The offspring must be able to produce young.
Mate and produce offspring.
Organisms that belong to the same species can reproduce a fertile offspring.
They must be able to reproduce, and their offspring must be fertile as well. So technically, because ligers are in fact fertile, tigers and lions are one species, regardless of the fact we classify them as two.
Offspring must compete for available resources in order to survive
-Produce fertile offspring -Successfully interbreed
Organisms are grouped into species according to their outer similarities so ducks and geese must vary enough to be categorized differently.
Organisms that belong to the same species can reproduce a fertile offspring.
they can produce fertile offspring

No it is not true.....The offspring of a horse and a donkey is a mule
interbreed and produce fertile offspring.

The origin of new species. To be considered a member of a singe species, organisms must be capable of reproducing and producing viable offspring. Once they have evolved to become reproductively isolated, they can no longer fulfill these requirements and are considered separate species.
genes
The classification of organisms from general to specific goes: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Therefor, two species the same Genus MUST be members of the same Family. However, a Family may consist of several different Genus, so species in the same Family are not necessarily members of the same Genus.
Depends on species.
The phenomenon of over-population, according to Darwin's theory, starts the whole process of evolutionary transformation of organisms. Overproduction is the main laws of natural selection ,it is the ability of a species to produce far more offspring than can survive. The number of organisms of each species are born into the world, more than the number of them, which can find their own food to survive and leave offspring, yet the number of each species in natural conditions is fairly constant. Therefore, it must be assumed that most of the offspring in each generation dies. If all the descendants of a species to survive and reproduce, then pretty soon they would be supplanted all other forms in the world.
