Show Answer
Answer:
Correct Answer: C
Solution:
In marine biology, the terms given in the options are used to classify organisms based on their lifestyle or location in the ocean:
Option A: Plankton - Plankton are the diverse collection of organisms found in water (or air) that cannot propel themselves against a current. They provide a crucial source of food to many large aquatic organisms, such as fish and whales.
Option B: Sedentary - Sedentary organisms are those that do not move about; they stay in one place. Many benthic organisms are sedentary.
Option C: Pelagic - This is the correct answer. Pelagic animals are those that live in the water column, away from the bottom of the ocean and the shoreline, and can swim freely. They include fish, whales, and many other marine species.
Option D: Benthic - Benthic animals live on the bottom of the ocean, either on the surface (epifauna) or burrowed into it (infauna). They include organisms like crabs, lobsters, and sea cucumbers.
