A snapping turtle will need a box or aquarium to live in. He will need food and water and some rocks and plants.
They can just live in an aquarium with the normal pebbles on the bottom that all fish live in.

mostly water and land you'll need a water pan for the turtle to soak in whenever he wants to. Feed fruits and veggeis, and earthworms and insects. They like dirt or mulch to dig into.
A turtle that won't eat is probably sick. It could be as simple as insufficient warmth. Consult an expert at the pet store about sort of temperature a turtle aquarium should be. You may also need to see a vet.
Aquarium plants can typically survive in a bag for up to 1-2 days before they need to be planted in an aquarium to ensure their health and growth.
Water if your turtle is aquatic or sand if it's a land turtle, a large rock for basking, a food dish, fresh water dish, and a basking lamp to set on top. Plastic or real plants are not necessary but make the habitat more appealing.
10 gallon if its only 2 inches and a 20 gallon for 4 inches
A land turtle needs water to drink, but not to swim in. Aquatic turtles live in the water, but they need to come out of the water several times a day to dry off their shells. If they don't, the shell will grow fungus and mold and will become infected.
Salt water hermit crabs need to live in ocean water that has been properly set up (like a reef aquarium). Land hermit crabs need access to both fresh and salt water but live the majority of their lives on land.
yes, is the short answer. but there is a lot more to it than that
Yes. The turtle will get exhaused swimming all the time, and even if the water is shallow enough for the turtle to stick it's head up to breathe without swimming, not having a spot to dry off and bask will cause the turtle to not be able to digest its food and fungal infections, outside and in, will occur.
