Question

We know that animals can be separated into two big groups: vertebrates and invertebrates. An example of each would be a horse and a horse fly. Even though these animals are very different structurally, they have several things in common. Both animals MUST have a method for ____________ because they are both classified as heterotrophs.
A) moving
B) using oxygen
C) getting food
D) reproduction

Answer 1

The answer is C since heterotroph means they don't have a way of making food

Answer 2

The right answer is C) getting food.

A heterotrophic characterizes an organism that provides for its subsistence by assimilating organic substances (from external sources) and incapable of producing these organic substances from mineral matter. Its carbon source is organic matter because a heterotroph can not fix carbon. By definition, heterotroph is opposed to autotroph.
