A truck accidentally leaks a large amount of oil into the habitat where flamingos, shrimp, and algae live. The oil spill resulted in most of the shrimp and algae dying off. How will this affect flamingos?

There colour will be less Pink.

Explanation:

The bright pink color of flamingos comes from beta carotene, a red-orange pigment that’s found in high numbers within the algae, larvae, and brine shrimp that flamingos eat in their wetland environment.

Which is now not present due to death of shrimps and algae.

if the shrimp and algae died off then the flamingos wont have any food  and will also die off

Explanation:

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)
