Is the biological domain animalia autotrophic or heterotrophic

Biological domain Animalia is heterotrophic

Option B

Explanation:

The Animalia kingdom follows the heterotrophic  mode of nutrition which means it depends on other organisms for their nutrition while autotrophs produce their own food. Carbon is the main source of energy. The heterotrophs get carbon from consuming these organic resources.

The cells are eukaryotic and they are multicellular organisms.They do not have a cell-wall. They intake large molecules and using their different organ system break down the food into simpler substances which provides nutrition and energy for the organism to survive.
