In some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called ligers. male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. the natural differences in the ranges of wild tigers and lions is an example of

Habitat isolation

Explanation:

It is a type of reproductive isolation between species, also referred to as allopatry, where they are kept apart by geographical barriers such as in this case, the large ranges that do not overlap. The behavioral difference between tigers and lions is a type of sympatry reproductive isolation  where even though the two species encounter frequently, behavioral isolation prevents them from  interspecies reproduction.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
