Read the following scenarios carefully and explain how natural selection will occur in each.
IrinaK [193]

Answer:

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.
