Waves transfer energy from the wind to the water environment, it played a major role in the survival of ocean life. Ocean waves function to clean the surface and help to oxygenate the water below the surface.
Waves also help to carry nutrients for marine animals along the shorelines, it has a great impact on habitability for various species of the marine environment. It breaks sediments from shorelines and deposits them to others, which result in the formation of beaches of sand and gravel that support a variety of species that live on rocky seashores.
Tides and currents affect and influence the natural world and human society. Tides and currents carry nutrients, moderate temperatures, and influence conditions in numerous ecosystems. The relationship between society and tides and currents is obvious as coastal cities built to withstand prescribed levels of tidal surge are now being impacted by record breaking tidal surges, and the building of solid coastal structures do not allow waves to dissipate energy on land but deflect their energy to other coastal areas along the shore.
Fish will eat tadpoles if they can get to them. The only way to stop them would be to give the tadpoles a space that the fish can't get to, like a shallow area with a barrier (plastic mesh would work but make sure the fish can't get caught in it) or lots of plants, or make a separate wildlife pond.
