Marine ecosystem
Shark
Sharks are the apex predators in marine ecosystems, which means they have few natural predators and feed on animals below them in the food web. Sharks limit the abundance of their prey, which then affects the prey of those animals, and so on throughout the food web.
Community
Tuna consuming large amounts of fish from schools. Piranhas in a feeding frenzy to eat a larger fish or animal. Lionfish attacking large numbers of reef fish.
Predation
Sharks
sharks are responsible for keeping the intricate ocean ecosystem in balance. As apex predators sharks keep everything below them in harmony.
Keystone Species
sea anemones and clownfish, barnacles and the various larger creatures they grow on, some shrimp and gobies, and remoras and sharks.
Commensalism
Organisms
Orginisms
Plankton are tiny organisms that are swept along on currents. Phytoplankton are tiny plant-like organisms. ...
Nekton are organisms that go through the water under their own power. Fish and marine mammals are nekton.
Benthos bury in the sediment, attach to rocks, or crawl over the seafloor.
parasitism on reefs is the tongue-eating louse of the species Cymothoa exigua.
Parasitism
Species
Algae.
Birds.
Invertebrates such as crabs, shrimp, oysters, tunicates, sponges, snails, and insects.
Fish.
Dolphins.
Manatees.
Reptiles such as sea turtles, land turtles, alligators, crocodiles, caimans, snakes, and lizards.
Species
hen both species living closely together benefit equally from their relationship. like Clownfish and anemones or Pistol shrimps and gobies.
Mutualism
Habitat
coastal zones, intertidal zones, sandy shores, rocky shores, mudflats, swamps and salt marshes, estuaries, kelp forests, seagrasses, and coral reefs. In addition, in the open ocean there are surface waters, deep sea and sea floor.
Habitat
effectively shrinks the size and benefits of no-take zones.
Edge Effect.
Competition
Organisms from different species compete for resources as well, called interspecies competition. like sharks, dolphins, and seabirds often eat the same type of fish in ocean ecosystems
Competition
Timeline
marine biology can be traced as far back as 1200 BC
Timeline
Niche
Niche
the way which an organism fits into an ecological community or ecosystem. like the way the shark fits in the Marine ecosystem and is not to over poplated.
