Answer: The words that make up the predicate adjective are D. strange and exotic.
Explanation: A predicate adjective is an adjective that comes after a linking verb, a verb that expresses a state of being and links the subject to the predicate of the sentence. In that way, a predicate adjective modifies the subject of a sentence. In the case of the sentence provided, the linking verb is "seems"; therefore, the predicate adjective is "strange and exotic" since it follows the linking verb and it refers back to the subject of the sentence ("Marine life on the ocean floor").
