Environments play a big role in how different animals change and survive. They adapt in three main ways: structure, behavior, and body functions.

1. Structural Adaptations:

   • Animals in cold places, like polar bears, have thick fur and a layer of fat. This helps keep them warm in super cold weather, which can drop to -30°C.
   • Animals in deserts, such as camels, have long legs and special kidneys. These help them lose less water. They can even survive losing up to 25% of their body weight from not drinking!

2. Behavioral Adaptations:

   • Many birds migrate, or move to different places, to survive. For instance, the Arctic Tern flies an amazing 71,000 km each year to find better breeding and wintering spots.
   • Some desert animals, like the fennec fox, are active at night. This helps them avoid the hot sun during the day.

3. Physiological Adaptations:

   • Some fish, like the Antarctic icefish, can create special proteins that act like antifreeze. This helps them live in freezing waters.
   • Cacti use a unique way of making food called CAM photosynthesis. This allows them to take in sunlight at night when it's cooler, helping them save water.

All these adaptations show how life can be really different and unique, depending on where animals live.
