Which term denotes a factor that limits biological processes, growth, or distribution in an environment?

• A. Limiting Factor
• B. Kingdom
• C. Food Web
• D. Hadal Zone

Answer: (A)

A factor that limits biological processes, growth, or distribution in an environment is called a limiting factor. This means any abiotic or biotic condition that prevents a population from growing or spreading beyond what the environment can support. Examples include scarce nutrients, low oxygen, extreme temperatures, or high predation—conditions that slow metabolism, reproduction, or movement and keep organisms confined to particular areas where they can survive. This idea helps explain why populations have a carrying capacity and why species occur only in environments that meet their needs. The other terms describe entirely different concepts: a kingdom is a major taxonomic category, a food web maps who eats whom, and the hadal zone refers to the deepest part of the ocean.
