Compared to the linnaean system of classification, what is the advantage of classifying species into clades?

clades show the evolutionary relationships between species.

Explanation:

A clade is a term that is defined as organisms that share a derived character from a group that includes the most common ancestor and its descendants. Cladistics is a type of classification that is based upon phylogeny but does not show the historical event, and has no time scale. It is strictly monophyletic, and it produces a cladogram which shows all the evolutionary relationships among species and the evolutionary lineages split from common ancestors. The Linnaean classification system focuses on the physical traits of species, has a time scale.  

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
