Detailed explanation-1: -It is a myth that peonies require ants to bloom. The relationship between peonies and ants is a type of mutualism in which two organisms of different species benefit from the activity of one another. Peony flowers provide food for ants and in turn, the ants protect the blossoms from other floral-feeding insects.

Detailed explanation-2: -Acacia ants have coevolved with acacia plants to provide the plant with protection from other insect and plant species. In return, the acacia plant provides the ant and its larvae with nutrients and shelter.

Detailed explanation-3: -The term coevolution is used to describe cases where two (or more) species reciprocally affect each other’s evolution.

Detailed explanation-4: -A kit fox lives in the desert and has large ears with greater surface area that keep the fox from getting overheated. The red fox lives in the forest and has a red coat that keeps it camouflaged.

Detailed explanation-5: -New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups.
