3)define sedimentation
Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism.
4)how does aquatic animals respire
Terrestrial (land) animals, inhale air through their noses, mouths, and even their skin, to bring oxygen to their lungs. Water has oxygen too. Fish get the oxygen their bodies need by pumping water over their gills. That's why fish keep opening and closing their mouths all the time: they're breathing.
