What is a biome?

A biome is defined as a large ecological area on Earth’s surface that is characterized by specific climate conditions, distinct types of flora (plant life), and fauna (animal life). This definition encompasses the diverse ecosystems found within these larger regions, illustrating how climate plays a crucial role in determining the types of living organisms that can thrive there.

For example, a desert biome features arid conditions with limited rainfall, supporting specialized plant and animal species adapted to such an environment. In contrast, a rainforest biome is characterized by high humidity and abundant rainfall, leading to rich biodiversity.

The other options do not accurately describe what a biome represents. While some mention specific characteristics of ecological areas or organisms, they fail to capture the broader scale and ecological significance that biomes encompass as defined by climate and community composition. Therefore, recognizing the defining characteristics of biomes is essential for understanding ecological relationships and environmental science.
