Raquel lives in a coastal community near a mountain glacier in Alaska Over the past several years she has observed a decline in
local marine fish populations off the coast. She performs an investigation and concludes that fresh water entering the manne
ecosystem from glacial melt is causing marine fish to move further out to sea.
Raquel wants to extend her investigation to determine how glacial melt affects marine fish Which question would be best to ask
next?
A. Does fresh water disrupt the ability of marine fish to maintain homeostasis?
B. Does fresh water positively or negatively affect marine fish?
C. To what extent have coastal marine fish populations declined?
D. Can marine fish better maintain homeostasis in shallow or deep ocean water?
