Document Summary
Time taken for one wavelength to pass a fixed point. New ocean instruments and satellites show that they exist. Winds do not always blow in the same direction. Create complex patterns of wave heights and wavelengths. Waves can travel huge distances across ocean. As they break at the shore they release their energy surf zone. Waves often approach the shore at an angle but bend to align parallel to shore. Waves are usually not completely parallel to the shoreline. Results in movement of sand along the beach. Autotroph: capture energy and store it as sugars, energy form the sun. Heterotroph: obtains energy by decomposing or consuming another organism, feeding strategies, suspension feeding, deposit feeding. Organisms feed on dead and decaying organic matter in sediments: carnivorous feeding. Energy is transferred from organism to organism through food chains. Organisms are classified by how many steps they are away from the original source of energy: trophic levels.
