Defining Vocabulary
Let's define our answer choices given to us:
0. Population,: A population is the amount of a specific species that is present in an area.
,
1. Ecosystem,: An ecosystem is all the living and nonliving sections that are within an area.
,
2. Biome,: A biome describes a region that consists of all the living and nonliving sections as well as the ,climate, of the area.
Applying Definitions
Let's apply the definitions we found earlier to the context of our question:
We are given that there is "a large group of ecosystems that share the same climate and have similar types of communities".
We know that the only vocab that fits this description will have to be C. Biome since the context mentions climate.
Answer
