Question
- 'Organisms may be conformers or regulators'. Explain this statement and give one example of each.
- Why are there more conformers than regulators in the animal world?
✓
Answer
- Some organisms are called conformers because they cannot maintain constant internal environment, e.g. plants. On the other hand, certain organisms are called regulators as they can maintain their internal environment in response to external conditions, e.g. humans.
- In the animal world, conformers are more than the regulators because thermoregulation is energetically expensive for many organisms. This is specially true for small animals like shrews and humming birds. Heat loss and heat gain is a function of surface area. Since, small animals have a larger surface area relative to their volume, they tend to loose body heat very fast.
