Final answer:
Parental care The energy and time dedicated to offspring production and care is known as parental care. Fecundity, the reproductive capacity of an individual, is inversely related to the level of parental care provided. Species with high fecundity usually invest less in parental care, whereas those with fewer offspring provide more intensive care.
Step-by-step explanation:
The energy and time expended constructing and caring for offspring is known as parental care.

The energy and time expended constructing and caring for offspring in the animal kingdom is known as parental care. This investment in offspring varies greatly among species, and there is a trade-off between the number of offspring produced and the level of care given to each. Fecundity, or the potential reproductive capacity of an individual, is inversely proportional to the amount of parental care provided. Species with high fecundity, such as many marine invertebrates, tend to invest very little in parental care, relying instead on the production of numerous offspring to ensure the survival of the species. Conversely, species that produce fewer offspring, like many mammals including humans, tend to provide extensive parental care, sometimes at the expense of their own health.
Through the mechanism of natural selection, species have developed life history strategies that optimize their energy allocation for growth, maintenance, and reproduction. It is a delicate balance, where the evolutionary fitness of an organism is influenced by how it distributes its energy budget between producing offspring and caring for them. Mammals like kangaroos and pandas, with few offspring, illustrate how high parental care can be essential for the development and survival of their young, despite the high energy cost and potential risks to the parents' health.
