Question

Mammals have a large amount of parental care, where one or both parents assist with the nurture of the newly-born offspring. Female wolves nurse and protect their pups for months. Chimpanzee offspring are cared for by the parents for several years. Although mammals have fewer offspring per reproductive event than fish, reptiles, and amphibians, their survival throughout their juvenile period is much higher. However, there are a few species of tropical frogs that lay eggs, but both parents tend to care for the offspring after they hatch. The male frog guards the eggs while the female frog assists in feeding the larvae after they hatch. Based on the passage, what makes a researcher infer that the survival rates are higher for tropical frogs than other frog species in general?

Answer 1

Biparental care allows the energetic demands to be shared between both parents, which can improve the number of surviving offspring
