Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that influence life forms vary with location within ocean systems. Oceanographers divide the ocean into five broad vertical zones as seen in the chart above. Compare the characteristics of the five zones. The giant tube worms, Riftia pachyptila, pictured here, have a red "plume" at the tip of their free end which is an organ for exchanging compounds with the environment. The tube worm does not have many predators. If threatened, the plume may be retracted into the worm's protective tube. The plume provides essential nutrients to bacteria living inside the worm. Tube worms have no digestive tract, but the bacteria, which may make up half of a worm's body weight, convert the oxygen, hydrogen sulfide, carbon dioxide, taken in by the plume, into organic molecules on which their host worms feed. Compare this information with the information in the chart. Where could these worms live?

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.
