What are 3 different pond zones?

- Deep water zone
- Littoral zone
Name all of the ocean zones and 2 organisms that live in each zone.
- The Intertidal zone (Sea Stars and Anemones)
- The Neritic zone (Sea Turtles and Dolphins)
- The Oceanic zone (Whales and Squids)
- The Benthic zone (Sea Urchins and Worms)
True or False? Intertidal areas have mud flats and rocky shores that are habitats to worms, and crabs.
True, but they also have sandy beaches that are habitats to worms, clams, crabs, and plankton.
True of False? Coral reefs are warm areas in the oceanic zone, made of small animals called corals they live in large groups and leave behind skeletons.
False. Coral reefs are warm shallow areas in the neritric zone, made of small animals called corals, they live in large groups and leave behind skeletons, for small fishes, algae, sea stars, sea urchins, and sponges.
True or False? Estuaries are places where salt water rivers meet each other, the animals have to adapt to changing salt levels, and there is almost NO plankton for animals to eat.
False. Estuaries are places where salt water meets fresh water, the animals have to adapt to changing salt levels, and there is A LOT OF plankton for animals to eat.
True or False? The Sargasso Sea is located in the middle of the Atlantic, the sea is filled with rafts of sargassum and algae, and animals hide in the sargassum for protection.
True.
