Q.What are the ways by which organisms respond to abiotic factors?

Step 1. Regulate: some organisms maintain homeostasis by physiological means, keeping body temperature and ionic/osmotic balance constant regardless of the external environment — mainly birds, mammals, and a few lower vertebrates/invertebrates.

Step 2. Conform: most animals cannot maintain a constant internal state, so their body condition (e.g., body temperature, or osmotic concentration in aquatic animals) simply changes along with the ambient environment.

Step 3. Migrate: organisms move away temporarily from a stressful habitat to a more hospitable area, then return once the stressful period has passed — as Siberian cranes do, wintering at Vedanthangal in Tamil Nadu. …

List and briefly define the four response categories: Regulate, Conform, Migrat …
