I would say that the Rocky Mts were the youngest of all these mountain ranges as they were created between 80-55 million years ago during the Laramide Orogeny and also they are generally much taller than the other mountain ranges mentioned here which is a characteristic of young mountain ranges and their features are sharper as they haven't been eroded the way most of these others have so have been subject to erosion for less time than the others.
Answer:
The per capita birth rate of the population will increase.
Explanation:
Fecundity refers to the ability of an organism in order to produce more number of offsprings. This leads to the increase in the number of population of lizards which is facilitated due to the increasing rainfall. In addition to this, the high abundance of rainfall also allows the number of predators to increase as a result of which it becomes difficult for them to survive.
From the above condition, it can be generalized that the population of lizard will increase at a much higher rate.
