the correct order of stages in the primary succession of a volcanic island environment is illustrated by
a)
shrubs-mosses-coconut trees-sea grasses
b)
volcanic rock-lichen-mosses-sea grasses
c)
volcanic rock-shrubs-coconut trees-sea grasses
d)
volcanic rock-sea grasses-coconut trees-shrubs

I think the correct answer from the choices listed above is option B. The correct order of stages in the primary succession of a volcanic island environment is illustrated by volcanic rock-lichen-mosses-sea grasses. In primary succession the first organisms (lichens) to attach to the rock are called pioneer species. Mosses are generally included as pioneer species because they require almost no soil to grow. Then, sea grasses grow. Hope this answers the question.
