What are the different methods that marine animals use to obtain food

Marine mammals use sound in a variety of ways while feeding. One well-known example is echolocation, in which animals produce short pulses of sounds that are reflected back when they strike an object.

Deposit feeders pass sand, mud, water or sediment into their mouths

Suspension feeders catch food or organic material from the water using tentacles or spiny arms

Filter feeders; capture food that is suspended in the water by creating a current within them for the water to flow through.

Predators actively seek out their prey items. In the ocean, some predators can be adapted to blend in with the surrounding area and wait for a prey item to pass by or they can be adapted to move quickly to chase down prey.

Explanation:

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

the answer is 1. photosynthesis. glad to
