A micro-environment is defined as:

A micro-environment is defined as:

• A. Affects multiple animals at once.
• B. It affects individual animals uniquely.
• C. It is permanent.
• D. It is the population-level effect of climate.

Answer: (B)

Micro-environment refers to the small-scale conditions that an individual animal actually experiences, such as the exact spot in a pen, nearby animals, or a local microclimate around it. Because each animal lives in a slightly different immediate surroundings, the effects of those conditions can be unique to each individual. This is why the statement that it affects individual animals uniquely best describes micro-environment. In contrast, something that affects many animals at once points to a broader, macro environment; permanence would imply a fixed condition, which isn’t inherent to micro-environment, and a population-level climate effect describes broader, not individual, influences.
