Question

The plants and animals that cannot maintain a constant internal environment are called:

• A. Regulators
• B. Migrators
• C. Conformers
• D. Suspenders

Answer 1

The Correct Option is C

To identify organisms unable to maintain a stable internal state, one must grasp how living things interact with their surroundings.

Environmental biology classifies organisms by their approach to internal environment regulation amid external shifts. The main classifications are:

• Regulators: Organisms that preserve a steady internal state despite external fluctuations, utilizing internal controls for bodily functions (e.g., mammals, birds).
• Migrators: Organisms that relocate to escape harsh environmental conditions (e.g., birds migrating south for winter).
• Conformers: Organisms whose internal environment mirrors external conditions, lacking active internal regulation (e.g., most plants, some aquatic life).
• Suspenders: Organisms that enter dormancy to endure adverse conditions, like hibernation or seed dormancy. 

Based on this, organisms that cannot maintain a consistent internal environment and instead adapt to external conditions are classified as: Conformers
