Are cownose rays autotroph or heterotroph?

The autotrophs are those living organisms which are capable of making their own food using the sunlight. The autotrophs are not dependent on others for food. The heterotrophs are the organisms who cannot make their own food and are dependent on other organisms to fulfill their food needs. The cownose ray is an eagle ray species, which is a heterotroph.

Hence, the answer is 'Cownose is a heterotroph'.
