Final answer:
Meiosis has a higher energy cost due to the complex processes of crossover, random assortment, and fertilization, which are crucial for producing genetically diverse offspring in sexual reproduction.
Step-by-step explanation:
The statement that best describes the cost of meiosis is that the production of haploid gametes for sexual reproduction has a higher energy cost than direct production of diploid offspring. In sexual reproduction, variation is introduced into offspring through mechanisms like crossover, random assortment of homologous chromosomes, and random fertilization, which are all present in meiosis.
Each of these mechanisms adds a layer of complexity and energy requirement to the reproductive process. This contributes to the evolutionary success of sexual reproduction despite the higher energy cost and reduced number of offspring compared to asexual reproduction, as it increases genetic diversity.
