Which is a shared characteristic of all animals? a) they are autotrophs b) they are vertebrates c) they are invertebrates d) they are heterotrophs

The answer is D they are heterotrophs

D) they are heterotrophs

Explanation:

This means that they get the nutrients (nitrogen, carbon, etc.) and the energy they need to live through plants or other animals, since they do not have a system for the production of their food. All animals need carbon for the proper functioning of their basic processes, such as growth, development and reproduction.
