Is a blue tit a producer?

A producer, or autotroph, is an organism which synthesises its own 'food' from external energy sources. The most common type is the photoautotroph, a plant or alga which photosynthesises, that is it creates carbohydrate molecules from carbon dioxide fixing using the energy absorbed from the sun. Other types include the chemoautotrophs, which create organic molecules from chemicals nearby, because they exist near volcanic vents underwater where there is no light.

The blue tit is not a producer as is does not produce its own carbohydrate molecules.
