Feeding and mating could be tied to tidal cycles for several organisms that occupy tidal basins or shorelines.
Crabs live from the bottom of the oceanic trenches to the top of the inter-tidal zone, to some cases of land Crabs such as on Christmas island. The highest concentration of crabs corresponds to the highest concentration of available food which is at the mid-tidal zone.
Oysters.
no!
Some that live in the bottom of the ocean, where no sunlight can reach it.
Tides can affect marine organisms by influencing their feeding, breeding, and behavior patterns. Organisms may time their activities with the tidal cycle to optimize feeding opportunities or avoid predation. Some species rely on tides to help disperse eggs and larvae for reproduction. Tidal currents also impact the distribution of plankton and nutrients that form the basis of marine food webs.
Star fish could live in the kelp, sea on the rocky floor.
Niche
Organisms in the near shore zone have developed various adaptations to cope with tidal patterns. Many species, such as barnacles and mussels, can close their shells to retain moisture during low tide, preventing desiccation. Others, like certain fish and crabs, time their feeding and reproduction activities to coincide with high tide when food is more abundant. Additionally, some plants, like salt marsh grasses, have specialized root systems to withstand varying salinity and water levels.
There are some organisms that make there own food and that don't need vitamins from the sun.
there are many organisms that do not require sunlight to live but then there are some that need hosts
Both yes and no. Some tidal energy is very effective to the human body and some do not
