Question

what is faunal succession? *
the study of how an ecosystem develops over time
the process of fossilization in a specific rock type.
the idea the fossilized organisms succeed one another in a definite and recognizable order through geologic time
extinct species are replaced by more advanced species in the same location

Explanation:

Faunal succession is a principle in geology. It states that fossilized organisms follow a definite and recognizable order through geologic time. This is a key concept in relative dating of rocks. The first option refers to ecological succession (not faunal). The second option is about fossilization process in a rock type (not faunal succession). The fourth option is a mis - representation as it's about the order in the fossil record (not just replacement by advanced species in a location).

Answer:

The idea the fossilized organisms succeed one another in a definite and recognizable order through geologic time
