Question 5 options:

Cold water lowers dissolved oxygen levels.

Currents prevent accumulation of most organic matter.

Few animals are adapted to withstand high-speed water.

Frothing water reflects sunlight away from autotrophs.

Answer 1

"Few animals are adapted to withstand high-speed water" explains the few animal species live in a fast-flowing river .

Step-by-step explanation:

• Animals adaptation are burrowing in sediments which helps mussels to avoid ever changing currents.

• Broad foot to snail stick to rocks where the running water is cool and clear and has high oxygen level.

• Other adoption are slow metabolism fast movement speed. Animals like mammals, amphibians insects supports variety of adoption which lead them to exist in moving water.

• The animals in fast water are more cold resistance, this is why we don’t go for fishing in the equatorial region as the animals struggle in the slow and warm water.
