This is something that I used I found it when I was asking the same question myself
Answer:
Option (4)
Explanation:
The ‘climate envelope model’ is defined as a part of a major dispersion model of species that uses the climate parameters in order to make a predictions of total space that a species occupies in an environment.
This models represents the areas of climate that are suitable for species (both plant and animals) to exist. The variables that are commonly used in the species distribution models are climate type, land cover area, topography of the area and some other variable that are related to the species distribution model.
Thus, it can be considered that this model describes the range that a species can inhabit.
Hence, the correct answer is option (4).
Natural numbers are the counting numbers so: 1, 2, 3, 4, ...
whole numbers are the natural numbers PLUS 0: 0, 1, 2, 3, ...
