Answer:

- The sign cautioned swimmers to stay within the designated swimming area–adverbial phrase.

- The lifeguards on the beach watched the swimmers carefully–adjectival phrase.

- Children and their parents built sandcastles with tall towers–adjectival phrase

- Seagulls soared over the water, searching for food–adjectival phrase.

Explanation:

- The sign cautioned swimmers to stay within the designated swimming area:

In this sentence, the word "within" acts as an adverbial phrase telling us where the swimmers were asked to stay. And the words "stay within the designated swimming area" is a prepositional phrase since it uses the preposition "within".

- The lifeguards on the beach watched the swimmers carefully:

Remember, adjectives are known for ending with 'ly', and the word "carefully" modifies the sentence, telling us how the lifeguards watched the swimmers.

- Children and their parents built sandcastles with tall towers:

This is the case because the adjective "tall" is used in the sentence to modify the word "tower", in a sense telling us the type of towers built.

- Seagulls soared over the water, searching for food:

The adjective "searching" is used to modify the entire sentence telling us what the Seagulls soared the waters for.
