Is a hawk an autotroph

No. An autotroph (auto = self; troph = nutrition) is an organism that obtains the energy it needs to live and grow via energy from the sun (photoautotrophy) or energy stored in the chemical bonds of simple inorganic molecules (chemoautotrophy). An owl is regarded as a heterotroph (hetero = other) because it obtains the energy it needs to live and grow by consuming other living organisms, such as rodents.
