What are some adaptations of organisms that live in streams and rivers?

What are species adaptations?

In evolutionary theory adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. … This enables better survival and reproduction compared with other members of the species leading to evolution.

Why do organisms adapt?

All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem predators and other species that compete for the same food and space.

Which organisms are most likely to survive?
