Answer:
An animal's external structure tells us about where it might live or eat by showing different skin/fur/scale/feather colors.
Explanation:
This is the biggest give away for where they might live because they're skin/fur/scales/feathers will most likely blend in with their environment (camouflage) in order for them to survive. It can also tell us if it is a shady or light environment, because sunlight can change skin/fur pigment.
This is the biggest give away for what they might ear because some animals skin/fur/scales/feathers turn different colors depending on what they eat. Flamingos, for example, are pink because they eat shrimp.
Hope this answers your question!
