The correct answer is C. Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time.

Explanation:

In biology, the evolution refers to changes organisms and species go through over time which is usually prompted by changes in the environment and adaptative processes. Additionally, evolution can be studied from two main perspectives: microevolution and macroevolution. Microevolution focuses on studying the changes at a lower lever usually by studying individual organisms or population, but not all organisms of a species. On the other hand, macroevolution studies the evolution or changes in species or even a group of species. For example in a microevolution biologist might study birds evolution by analyzing individuals or a specific population, while from macroevolution all the species need to be studied.
