Question

which of these is a characteristic of k-selected species?
high parental care of offspring
generalized niches, eats anything
many offspring at one time
small body, no care of offspring

Explanation:

K - selected species are adapted to stable environments. They typically produce fewer offspring but invest more in parental care to increase the survival rate of their young. Generalized niches, many offspring at once, and small bodies with no care are characteristics of r - selected species. So "high parental care of offspring" is a K - selected trait.

Answer:

A. high parental care of offspring
