Question

What types of adaptations would be needed by organisms that live in a river.

Answer 1

Step-by-step explanation:

For fast moving currents of a river, they need the adaptation of being able to resist the currents to avoid being washed away. (Ex: Immature black flies) Whilst on slow currents of a river, they need the adaptation of being able to live on the water surface, according to the textbook. (Ex: Water striders)

Answer 2

If they live in a river, they would most likely need fins (to swim) and gills (to breathe under water)
