1. Polar Bear - Arctic Tundra: Polar bears thrive in the icy, frozen landscapes of the Arctic tundra, where they hunt seals on sea ice and have thick fur and layers of blubber to stay warm.

2. Tropical Rainforest - Macaw: The vibrant and diverse Amazon rainforest is home to the macaw, a colorful parrot that relies on the abundance of fruit and nuts for its diet. Their bright plumage helps them blend in with the foliage.

3. Coral Reef - Clownfish: Clownfish live in symbiotic relationships with anemones, which offer them protection from predators. They find their home within the colorful and teeming coral reefs, where they rely on the algae-based food chain.

4. Savanna - Lion: The African savanna, with its open grasslands and scattered trees, provides the perfect hunting grounds for lions. Their tawny coloration helps them blend in while stalking prey.
