Why Are Flamingos Pink?

Flamingos are not born with pink feathers; their color comes from their diet, rich in carotenoids found in algae and shrimp. These pigments are processed in the flamingo's body, turning their feathers pink over time. A similar process occurs in lobsters and shrimp when cooked. Humans can also experience skin color changes from consuming carotenoid-rich foods, a condition known as carotenosis.

What is the primary reason flamingos are not born with pink feathers?

• Their feathers are naturally gray.

• Their diet lacks carotenoids initially.

• They are sick at birth.

• They are born in a different environment.

Which compounds in flamingos' diet are responsible for their pink coloration?

• Carotenoids

• Vitamins

• Proteins

• Lipids

How do flamingos' digestive enzymes contribute to their pink coloration?

• By attaching pigments to proteins

• By detaching pigments from proteins

• By changing the shape of pigments

• By reflecting blue light

What happens to the pigments once they are free in the flamingo's body?

• They make the flamingo's beak red.

• They are incorporated into fats in feathers.

• They are excreted as waste.

• They turn the flamingo's skin blue.

What condition can occur in humans if they consume too many carotenoid-rich foods?

• Carotenosis

• Anemia

• Albinism

• Hyperpigmentation
