Human activity is not a natural factor that influences biogeographic patterns.

Temperature is the most important climate factor in determining the distribution of plants and animals because it affects their ability to survive and reproduce.

Loam is the most conducive to plant growth because it has a good balance of sand, clay, and organic matter.

A mountain range is the most likely to be a barrier to dispersal for plants and animals because it can be difficult to cross.

Self-dispersal is not a type of dispersal because it does not involve the movement of an organism from one place to another.

Endemic extinction is not a type of extinction because it does not involve the extinction of a species from its entire range.

Indomalayan is not a type of biogeographic realm.

Tundra is not a type of biogeographic province.

Asia is not a type of biogeographic region.

Polar is not a type of biogeographic zone.

Ocean is not a type of biogeographic barrier.

Desert endemism is not a type of biogeographic endemism.

Sundaland is not a type of biogeographic hotspot.

Protected Area is not a type of biogeographic conservation priority area.
