with its long tounge
A sea turtle is a consumer, because it cannot make its own food. It has to rely on other organisms for its food.
food and water
a sea turtle spend it time finding food and lay egg
They swim around and when they sea their food they swim towards it and snap it goes
pet stores sell marine turtle food but if you dont have any turtle food then they can eat fish (live or dead)

The leatherback turtle does not have competition for its food. This turtle mainly eats jellyfish and the venom from the jellyfish helps the turtle against predators.
The sea turtle is near the bottom of the food chain because it only eats plants. But it is debatable for the simple fact that nothing eats the turtle.
