Question

multiple-choice question why are the feathers of this flamingo pink? because they are sunburnt because of the algae they eat because they want to attract other flamingos because of the shrimp they eat

Explanation:

Flamingos' feathers get their pink color from the carotenoid pigments in the shrimp (and also algae) they consume. The option "because of the shrimp they eat" is correct as the carotenoids from shrimp (like brine shrimp) contribute to the pink hue. The "sunburnt" option is incorrect (feathers don't sunburn to get color), and "attract other flamingos" is not the reason for the color (the color is due to diet, not a mating - related attraction mechanism via color origin). The algae option is also a source, but among the given options, the shrimp - related one is a well - known key source for the pink color of flamingo feathers.

Answer:

because of the shrimp they eat
