Identify the simple adverb in the following sentence:The green iguana runs quickly on its wheel.

In the sentence "The green iguana runs quickly on its wheel," the simple adverb is "quickly."

Explanation:

Adverbs are words that typically modify verbs, adjectives, or other adverbs, often providing information about how, when, where, or to what extent something happens. In this case, "quickly" modifies the verb "runs," describing the manner in which the iguana runs. It gives us more insight into the action by indicating that the iguana is running in a fast manner.

While other types of adverbs, such as conjunctive or relative adverbs, can exist, simple adverbs are those that are standalone words and not complex or elaborated forms. Here, "quickly" serves that purpose effectively by enhancing the sentence's meaning without additional modifiers or phrases.
