Final answer:
Late reproduction is inversely related to fecundity because it increases the risk that an organism will not survive to reproduce, which decreases its reproductive potential compared to early reproduction.
Step-by-step explanation:
The condition that is inversely related with fecundity is b) Late reproduction. Fecundity refers to the reproductive potential of a species or the ability to produce offspring. An inverse relationship means that as one variable increases, the other decreases. Therefore, late reproduction is inversely related to fecundity because the longer an organism waits to reproduce, the higher the risk that it will not survive to actually reproduce or may have decreased reproductive capabilities. This is contrasted with early reproduction, where organisms have a greater chance of producing offspring, albeit often at the expense of their own growth and health.
Reproducing late in life often means having greater fecundity due to increased size or ability to provide parental care, but it comes with the risk of not surviving to reproductive age. This trade-off is a critical aspect of understanding life history strategies and the evolution of species as they maximize fitness and fill their ecological niches.
