Question

a species of owl feeds only at night and a hawk species feeds only during the day. what type of reproductive isolation is occurring between these two species that feed at different times? zygotic isolation gametic isolation temporal isolation

Explanation:

Temporal isolation is a pre - zygotic reproductive isolation mechanism. It occurs when two species breed or are active at different times (e.g., different times of the day, different seasons). In this case, the owl is active at night and the hawk is active during the day. This difference in activity times (temporal difference) prevents them from coming into contact during their reproductive periods, thus acting as a reproductive barrier. Zygotic isolation is not relevant here as it would involve issues after fertilization (if it occurred). Gametic isolation involves problems with gametes (e.g., sperm and egg) not being able to fuse, which is not indicated by the time - of - activity difference.

Answer:

temporal isolation
