Final answer:
Fecundity is the number of offspring produced per unit of time by an organism and is influenced by various factors such as parental care and the length of the reproductive period.
Step-by-step explanation:
Fecundity is the number of offspring produced per unit of time by an organism. It describes the reproductive potential of a species and is influenced by factors such as the presence or absence of parental care, the duration of an organism's reproductive period, and the death rate of offspring. Fecundity is inversely related to the amount of care given to individual offspring, with species that produce many offspring usually providing little or no parental care.
