Thinking about the energy pyramid, which kinds of organisms are more likely to be abundant in the fossil record?

Heterotrophs are the types of organisms which are  abundant in the fossil record

Explanation:

An energy pyramid is a pyramid where all the biological communities are connected in the manner in which the energy follows from one level to another. The food will travel from one tropical level to another tropical level. At the end of the pyramid is called base which is composed of the species called autotrophs.
