Seahorses occupy a middle position in their food chain. They are carnivores that feed on tiny crustaceans, such as shrimp. The shrimp feed on algae, which are near the base of the food chain. Seahorses are preyed upon by crabs and fish, which are eaten by larger fish. These large fish are hunted by apex predators, including sharks that are at the top of the food chain.Know More
Seahorses use their prehensile tails to anchor themselves to plants or coral. Because they are sedentary and camouflage easily, they can ambush their prey at any moment. When shrimp and other small organisms swim by them, seahorses quickly suck them in with their elongated snouts. They feed continuously and can eat as much as 3,000 brine shrimp in a day.
Seahorses are slow, rather inept swimmers that tire easily, so they use their natural camouflage to hide from predators. Seahorses are often captured as specimens for aquariums. Humans also fish for them in East Asia because the natives there believe that seahorses have medicinal properties. The Convention on International Trade in Endangered Species of Wild Flora and Fauna attempts to control the import and export of seahorses, although several nations have opted out of these regulations.Learn more about Marine Life
A food web is a comprehensive map of how energy moves, in the form of food, throughout an ecosystem, while a food chain is one specific path through the web. Most food webs on Earth derive their energy primarily, if not exclusively, from sunlight. That energy is captured by plants via photosynthesis and then distributed to the consumers in the environment.Full Answer >
Tiger sharks exist at the top of the food chain, and they prey on a wide variety of species, including fish, sea turtles and other sharks. Additionally, tiger sharks prey on sea-dwelling birds, catching them as they land on the water’s surface. Mollusks such as sea snails, conchs and whelks also serve as prey for the opportunistic sharks. Tiger sharks are also scavengers that have been known to eat garbage.Full Answer >
The American alligator, known to scientists as Alligator mississippiensis, is at the top of the food chain. Called an apex predator, American alligator adults feed on virtually every other creature that shares their habitat, but they fear nothing except for humans and larger alligators. However, its young are not so safe, and many baby alligators are consumed by a variety of aquatic predators.Full Answer >
The food chain of a producer is the sun, the primary consumer, the secondary consumer and the decomposer. The producer uses the sun and nutrients in the soil to make food, and animals that consume it eventually die and fertilize the soil.Full Answer >
