Which term best describes a broad ecological category defined by climate and typical organisms, such as forests or deserts?

• A. Biome
• B. Commensalism
• C. Community
• D. Species

Answer: (A)

Biomes are broad ecological categories defined by climate and the typical organisms that inhabit them, so forests and deserts illustrate different biomes because they reflect distinct patterns of temperature, precipitation, and the life forms adapted to those conditions. This view focuses on large-scale environmental patterns rather than on relationships between species or individual units. Commensalism is a type of interaction between species, not a description of a region. A community refers to all the populations living in an area and their interactions, not the climate-based category. A species is a single kind of organism, not the large-scale environmental grouping. So the term that best describes this broad category is biome.
