The statement is related to figurative language because it is a simile (a simile contains the words "like" or "as" to compare two unlike things), an alliteration (a phrase that has repeating vowel sounds at the beginning of two or more words in a sentence: "clinging like cobwebs"), and a personification (when an inanimate object is given human characteristics: "fear" was said to be "clinging").
The last one is not true. Only the second statement mentions how fragile the environment is that coral reefs exist in.The first statement focuses on erosion and pollution as causing the reefs to die.
