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:

All animals are heterotrophs. 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.
