Read the following scenarios carefully and explain how natural selection will occur in each. Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal). Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce, about 500 offspring are born but only 100 of them live long enough to reproduce themselves.

The correct answer is - Noctural worms have the advantage over diurnal due to the fact that the nocturnal worms are burrowing during the feeding time of birds.

Explanation:

Natural selection is the process in which organisms adapt according to environmental changes to increase their survival rate. Natural selection leads to natural changes in different organisms.

In this case, diurnal worms are forced by the natural selection here to adapt to the change if they want to survive. Here, natural selection works for the nocturnal and against the diurnal.
