Migration helps an organism cope with an unfavourable environment by
- A. temporarily moving to a more suitable habitat
- B. permanently eliminating environmental variation
- C. stopping all metabolism in the same place

Common mistakes in Abiotic factors and how organisms cope
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Assumes only internal physiology can buffer an abiotic stress.
- Uses the terms regulator, conformer and migrant interchangeably.
