Apply the idea of natural selection to explain the relationship between environmental change and the trait(s) of your species. Write a scientific explanation using the scientific ideas of natural selection and adaptation to explain the cause-and-effect relationship between environmental change and your species’ population. BE SURE TO INCLUDE EVIDENCE.

one centimetre is equal to 0.01 metres

the right option is; decreased genetic variation  

decreased genetic variation describes the effect of this environmental change.

genetic variation is the naturally occurring genetic diversities or differences between organisms of the same species in a population. genetic variation allows the survival and adaptability of a species when they encounter changing environmental conditions. when an endangered species reduces, it loses genetic variation which may not be restored even if the species rebound and will only be recovered through the gradual collection of mutations over many years.
