Is a sea turtle a decomposer?

No, a sea turtle is not a decomposer. Sea turtles are primarily herbivores or omnivores, depending on the species, and they play important roles as consumers in their ecosystems. Decomposers, such as fungi and bacteria, break down dead organic matter, recycling nutrients back into the environment. Sea turtles contribute to the health of marine ecosystems but do not perform the function of decomposing organic material.
