If a rocky island appeared out of the water from volcano activity, what type of organism would most likely live there first?

lichens and moss

Explanation:

Lichens are formed when there is a relationship between fungi and algae, that is, a symbiotic one, as it is a union that is advantageous for both. These organisms would probably appear if a rocky island appeared out of the water due to volcanic activity, because of all the humidity that would favor fungi and because of the presence of algae in the aquatic environment. Lichens reproduce asexually on rocks, soils, barks and tree trunks, through propagules called soredium that contain algae cells and fungi hyphae.

Mosses, in turn, live in humid and shaded environments. They can grow under different substrates such as soil, rocks, tree trunks and even walls. Some species of mosses form true green carpets, covering large areas. It would be very common for mosses to appear if a rocky island appeared out of the water due to volcanic activity, due to all the humidity in the place.

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.
