Explain how the salinity (salt concentration) of an estuary affect the kind of organism that live there? answer this question and i'll answer your guys

Most marine organisms have internal salt concentration higher than

freshwater and take on water by osmosis in estuaries

• Osmoconformers, e.g., molluscs, worms, maintain osmotic balance by

allowing body fluids to change with salinity of water

• Osmoregulators, e.g., fish, crabs, keep salt concentration of body fluids

more or less constant via active transport.
