Mutations are like genetic mutations. Say a bird species may usually have a orange beak but one bird was born with blue, that’s a mutation.
Adaptations are things you adapt to like plant species have adapted over the year to receive less and less water to live.
Natural selection is basically ‘killing off’ the weaker ones. Say a bird species has broad wings but mutations happened over time leading them to have small wings that do not allow flight, they may eventually all die off due to that. Extinction is if al those birds were to die off from that mutation.

Answer from: ling95

Sample Response: Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.

Answer from: Quest

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
