What do corals eat for kids?

They eat small animals called plankton as well as algae. The algae get their food from the sun by using photosynthesis. This is why coral reefs form close to the surface of the water and in clear water where the sun can feed the algae.

What do corals eat as food?

Corals get their food from algae living in their tissues or by capturing and digesting prey. Most reef-building corals have a unique partnership with tiny algae called zooxanthellae. The algae live within the coral polyps, using sunlight to make sugar for energy.

What do small corals eat?

Some corals eat zooplankton (tiny drifting animals) or small fishes. Others consume organic debris. Many reef- building corals derive their nutrition from zooxanthellae.

What do coral reef fishes eat?

Most reef fishes eat plankton during their juvenile stage and some continue to feed on plankton after they have matured. Planktivores feed either above the reef or feed near the reef or sandy bottom and may feed during the day or at night.

What animals feed on corals?

In addition to weather, corals are vulnerable to predation. Fish, marine worms, barnacles, crabs, snails and sea stars all prey on the soft inner tissues of coral polyps.

Coral: What Does it Eat?

What do corals need to survive?

Do any fish eat coral?

blue triggerfish "Coral eating" fish such as parrotfish, triggerfish and surgeon fish feed on the algae rather than the coral polyps themselves. Many do this by eating the rocky coral itself, extracting the food the need and grinding up rocky material and expelling it as sand.

What is the food web of the coral reef?

Some of the producers in the Great Barrier Reef food web are photosynthetic algae, phytoplankton, and seaweed. Some examples of primary consumers are corals, small fish, and zooplankton. Secondary consumers include crab, small fish, and clams. Tertiary consumers include larger fish, sharks, and octopuses.

What does a fish eat?

For example, fish eat a variety of insects including flies, mayflies, midges, crickets, grasshoppers, and beetles. Many fish also eat worms, including superworms, mealworms, bloom worms, leeches, and nightcrawlers. Some larger fish will prey on small rats, mice, snakes, frogs, turtles, and other, smaller fish.

Why do fish eat coral?

They eat coral which contains food sources they like such as polyps, worms and other small invertebrates. These fish usually mate for life and stay together with their offspring.

What is the best food for corals?

Do corals need food?

Strictly speaking, many coral reefs don't need to be fed supplemental food. In fact, a lot of corals get their daily nutrition through photosynthesis. This is where corals capture light and transform it into food for themselves.

Are corals carnivores?

Coral are carnivores. They use their long tentacles with stingers to catch and subdue their prey. They mostly feed on plankton, tiny creatures in the ocean's water.

Do corals eat phytoplankton or zooplankton?

Phytoplankton are the base of most marine food webs and the prey for zooplankton, a favorite food of corals.

Do corals eat bacteria?

All corals studied consume dissolved organic material, bacteria, and detrital material. This is more than can be said for any other food source, including zooplankton and light. Coral consume bacteria in a number of ways.

Is coral a plant or animal?

Corals are animals, though, because they do not make their own food, as plants do. Corals have tiny, tentacle-like arms that they use to capture their food from the water and sweep into their inscrutable mouths.

What plant do fish eat?

What do ocean fish eat?

Herbivores in the ocean eat things such as algae and flowering seagrasses. Many herbivores' diets consist of primarily algae. Most saltwater fish will eat both macroalgae and microalgae. Many fish eat red, green, brown, and blue algae, but some fish prefer certain types.

Do fishes sleep?

While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.

What are the two main sources of food on the reef?

Besides zooxanthellae, algae and seagrasses are the main types of plants in the coral reef ecosystem. These plants give food and oxygen to the animals that live on the reef. Seagrasses are especially important because they provide shelter for juvenile reef animals like conch and lobster.

What eats algae in the coral reef?

Shark species include lemon, nurse, Pacific blacktip, white-tipped reef, and zebra sharks. These sharks as well as rays generally eat crabs, shrimps, squids, clams, and small fishes. Parrotfish use chisel-like teeth to nibble on hard corals. These fish are herbivores and eat the algae within the coral.

What are 3 food chains in the Great Barrier Reef?

Seagrass, phytoplankton, and seaweeds are the producers. Primary consumers like clams, shrimp, zooplankton, and small fish eat the producers. Larger fish, rays, and octopi are the secondary consumers, and sharks are the ultimate predator in this ecosystem, eating many types of primary and secondary consumers.

Do starfish eat coral?

Normally, the starfish contribute to the reef's diversity by eating faster-growing coral species, which allow for slower-growing species to thrive. But at outbreak levels, the starfish are able to eat coral — a polyp that builds the limestone reefs on which they communally live — faster than the coral can reproduce.

Do dolphins eat coral?

Dolphins spend a lot of time foraging (looking for food) to obtain the energy they need to survive. Therefore, they are strongly dependent on the amount, distribution and health of their prey. Many of these prey species spend parts of their life on or around coral reefs.

Do crabs eat coral?

For many reasons, including climate change, coral reefs are dying around the world. But scientists say some crabs eat coral-choking seaweed and algae and may help with restoring coral reefs.
