Areas of mexico that can support agriculture are affected by the varying a. altitudes. b. longitudes. c. lowlands. d. animal species

I believe that the correct answer is D.)Animal Species

Animals reproduce , breed , and affect the agriculture.
Look up the word agriculture , you will see how my answer makes more sense.

My reason being is mainly because everything basically lives off of animals and if the are affected by anything and in any way start to decrease , the population will also.

I really hope that this helps you out a lot.
 

No one knows sorry. : )
