Question

can anyone answer this question plzz,,what would happen to an organism that live in a fast-moving river,if a dam was built on it?

Answer 1

Its lifestyle would change because the water will not move very fast. Its eating habits might also change.

Answer 2

The flow will stop greatly affecting not only the creature, but the other inhabitants, thus changing lifestyle and probably driving animals to death.

Answer 3

Hmm yes, that sounds about right. It is hard to answer without knowing the types of areas you have been learning about :)

The primary changes that building a dam would be (a) loss in system energy - so less 'power' for erosion, slower water etc.(b) loss in water in general and (c) a loss in the things that water would bring - food and oxgyen.

In a fast flowing river the organism would receive alot of food and the water would be highly oxygenated. When the dam is built it would loose supply of both of these. A negative impact on the organism would definitely be expected.

Answer 4

doesn't matter what kind of organism...a dam weighs several tons, and if it's built on top of the animal, it will be crushed. poor thing!

Answer 5

it would die!
