Which term describes a large naturally occurring community of flora and fauna occupying a major habitat such as forest or tundra?

• A. Biomes
• B. Aquatic ecosystem
• C. Terrestrial ecosystem
• D. Postemergence herbicide

Answer: (A)

Biomes are broad, naturally occurring communities of plants and animals defined by climate and dominant vegetation that occupy major habitats like forests or tundras. This makes the term the best fit for describing such large-scale, climate-driven areas. A terrestrial ecosystem is a land-based community and environment, but biomes operate at a larger, global scale with characteristic climate and vegetation patterns. An aquatic ecosystem refers to water-based environments, and a postemergence herbicide is a chemical for weed control, not a classification of natural communities.
