Question

Corals and anemones are

• A. Plants which cannot make their own food
• B. Plants which can move
• C. Animals which can make their own food
• D. Animals which cannot move

Answer 1

The correct option is D Animals which cannot move

If we visit a rocky shore at the beach during a low tide, we would see that many of the animals living there don't move. Biologists use the word "sessile" to describe animals that live like this. Barnacles, for example, live cemented to hard rocks. Once they choose a spot to settle on, they're stuck there until they die. Sea anemones and corals are also sessile. Some anemones are capable of moving around a bit but are considered sessile because for the most part, they tend to stay put. You can find sea anemones of all sorts living in tidepools on shores throughout the world.

Therefore, the correct answer is option D.
