Imagine a hypothetical population of elephants and rabbits in which both species remain at carrying capacity over many generations
Who would have more offspring that survive to be adults and reproduce during their lifetime, a mating pair of elephants or a mating pair of rabbits? Explain your answer.
The elephants and the rabbits will have the same number of offspring that survive to adulthood and reproduce. If the population is stable, then birth rate would equal death rate and the growth rates of the two populations would be identical. While the rabbits would have a higher birth rate, they would also have a higher death rate to maintain their constant population size at carrying capacity.
