How do freshwater invertebrates primarily eliminate ammonia?

Diffusion across their skin

Active transport through gills

Excreting concentrated urine

What is the osmotic challenge for freshwater animals?

They lose water to the environment

They gain excess water from the environment

They must produce ammonia

By what process does water move into freshwater fishes?

Active transport

Filtration

Osmosis

How do freshwater fishes primarily maintain salt balance?

Drinking large amounts of water

Actively pumping salt inward across their gills

Excreting salt through skin

Marine invertebrates release ammonia mainly by?

Diffusion across body surfaces or gill membranes

Active transport through skin

Excreting it in urine

Why do many marine invertebrates suffer less water balance issues?

Body fluids have solute concentrations similar to seawater

They drink seawater constantly

They excrete more salt through gills

What happens to marine fishes because their bodies are less salty?

They gain water from surroundings

They store water in tissues

They lose water to their surroundings

How do marine fishes maintain salt balance?

Storing salt in kidneys

Excreting salt across their gills

Absorbing salt from seawater

Which adaptation helps marine fishes conserve water?

Producing small quantities of urine

Drinking seawater

Producing large quantities of dilute urine

Freshwater fishes vs marine fishes: main difference in osmotic challenge?

Freshwater animals face water influx; marine face dehydration

Both face dehydration

Both gain water equally from environment
