The correct answer is C. Continent.
A biome is a large area of land or water with a particular climate and plant and animal life. Biomes are classified according to their dominant plant life, such as forests, grasslands, deserts, and tundra.
The climate of a biome is determined by its latitude, elevation, and proximity to water. Latitude is the distance north or south of the equator. Elevation is the height above sea level. Proximity to water affects the amount of rainfall and humidity.
The climate of a biome is the most important factor in determining the types of plants and animals that live there. For example, tropical rainforests are found near the equator, where the climate is warm and wet. The plants and animals that live in tropical rainforests are adapted to the warm, wet climate.
Continent is not as important as latitude, elevation, and proximity to water in determining the climate of a biome. For example, tropical rainforests can be found on all continents except Antarctica. The climate of a tropical rainforest is determined by its latitude, not by the continent on which it is located.
Therefore, the answer to the question “Which of the following has the least similarity when comparing two examples of the same biome located in different parts of the world?” is C. Continent.
