Answer:
Flora and Fauna, respectively
Step-by-step explanation:
Flora is the collection of all plants that are located in a specific geographic area, while Fauna is the same but with animals.
Flora and Fauna together are the bedrock of geographical ecosystems, and are also very important for human geography because humans use a number of plants and animals for several purposes, which implies that the flora and fauna of a place determine to a large extent the economy and culture of a human population that lives in a specific geographical area.
