Correct Answer: how many offspring are male.
biotic potential refers to the maximum growth rate that a population can achieve under ideal conditions, where there is no competition for resources, and no limitations due to predators or diseases. it is a critical concept in population ecology, used to understand the capacity of a species to increase in number. several factors contribute to determining the biotic potential of a population. these factors include the age at which organisms begin to reproduce, the frequency of reproduction, and the number of offspring that survive to adulthood. each of these elements plays a crucial role in how quickly a population can grow under optimal conditions.
the age at which organisms start reproducing is significant because it marks the beginning of the possibility for population increase. species that mature early and can reproduce soon after birth will have a higher biotic potential compared to those with a later onset of reproductive maturity. similarly, the frequency with which organisms reproduce affects the biotic potential. species that can reproduce multiple times a year or have shorter gestation periods can increase their numbers more swiftly than those that reproduce less frequently.
moreover, the number of offspring that survive to adulthood is another vital factor. high survival rates among the young mean that more individuals can reach reproductive age, thereby contributing to the future population growth. this factor is particularly influenced by environmental conditions and the availability of resources that support the health and growth of the young.
however, the sex ratio of the offspring—specifically, how many of them are male—does not directly influence the biotic potential. while the sex ratio can affect the mating dynamics within a population, it does not inherently limit or enhance the population’s capacity to reach its maximum growth rate under ideal conditions. the biotic potential assumes an environment where all individuals have an equal chance to reproduce and contribute to population growth, making the sex of the offspring irrelevant in this context. thus, when considering the factors that determine biotic potential, the sex ratio of the offspring is not a relevant factor and is correctly identified as the exception among the options provided.
