Corals and Coral Reefs

Coral reefs are the most diverse and beautiful of all marine habitats, and home to a myriad of animals that live in this complex biome. Coral reefs are under threat from climate change, ocean acidification, overuse of reef resources, and harmful land-use practices.

What happens if rainwater hits coral?

User Avatar

Asked by Wiki User

When rainwater, which may be polluted with sediments, chemicals, or pollutants, hits coral reefs, it can cause stress to the corals by reducing water clarity, introducing excess nutrients, and altering the pH balance of the water. This can lead to coral bleaching, reduced growth rates, and increased susceptibility to diseases. Additionally, runoff can also carry physical debris that can damage the coral structure.

When a ship sinks and is turned into an artificial reef does it matter what shape it is and what it is made of?

User Avatar

Asked by KillerArt

The shape and material of a ship can impact its suitability for being turned into an artificial reef. Ideally, a ship should be environmentally safe and able to create a habitat for marine life. Finding a balance between complexity for marine life and safety for divers is important in selecting a ship.

Corals have been known since ancient times and therefore there is no record of who first came across them.

Which water ecosystem has the fewest nutrients?

User Avatar

Asked by Subaitar34

The water ecosystem with the fewest nutrients is typically the open ocean. Nutrient levels in the open ocean are often low due to reduced mixing of nutrients from the seafloor and limited input from land sources, resulting in low productivity compared to other ecosystems like rivers, lakes, or coastal areas.

How do seahorses affect the coral reef?

User Avatar

Asked by Wiki User

Seahorses help maintain balance in the coral reef ecosystem by preying on small crustaceans that could otherwise overpopulate and damage coral. They also serve as prey for larger predators, contributing to the food chain dynamics in the reef. Additionally, seahorses play a role in nutrient recycling by excreting waste that can benefit the reef's overall health.

What are the coral adaptations?

User Avatar

Asked by Wiki User

Coral have evolved adaptations such as symbiotic relationships with algae for energy, calcium carbonate skeletons for structure, and tentacles with stinging cells for defense and feeding. They also reproduce through spawning events, where they release eggs and sperm simultaneously for fertilization.

What are endometrial polyps?

User Avatar

Asked by GaleEncyofMedicine

Endometrial polyps are growths in the lining of the uterus (endometrium) that are usually noncancerous. They can cause symptoms like abnormal bleeding, especially between periods or after menopause. Treatment may involve removal of the polyps if they are causing symptoms.

A region of ocean water having the same temperature and a salinity throughout is a what?

User Avatar

Asked by Wiki User

A region of ocean water with the same temperature and salinity throughout is called a water mass. These water masses occur due to factors like water density, mixing, and currents, and serve as distinct bodies with specific characteristics in the ocean.

What is the algae that has a symbiotic relationship with the reef builders?

User Avatar

Asked by Wiki User

Zooxanthellae is the algae that has a symbiotic relationship with reef-building corals. These algae live within the coral's tissues and provide energy through photosynthesis, while the coral provides shelter and nutrients to the algae in return. This symbiotic relationship is crucial for the health and growth of coral reefs.

What is a non- example of photosynthesis?

User Avatar

Asked by Wiki User

An example of a non-example of photosynthesis would be the process of cellular respiration, where organisms such as plants, animals, and fungi break down organic molecules to produce energy in the form of ATP. This process is the opposite of photosynthesis, as it involves the consumption of oxygen and the release of carbon dioxide.

How do the tiny animals that live on coral reefs feed and what can possibly eat them?

User Avatar

Asked by Wiki User

Tiny animals on coral reefs feed by filtering water for plankton and algae, grazing on surfaces, or preying on other smaller organisms. Possible predators of these tiny animals include fish, crustaceans, and various invertebrates such as sea stars and sea cucumbers.

What non living things are there in the coral reef?

User Avatar

Asked by Wiki User

Examples of non-living things in a coral reef include rocks, sand, shells, sunken ships, and artificial structures like buoys or fishing equipment. These elements form the physical structure of the reef, providing habitats for marine life to thrive.

What is the geographical distribution of the ocean?

User Avatar

Asked by Wiki User

The ocean covers about 70% of the Earth's surface and is divided into five main basins: the Pacific, Atlantic, Indian, Southern, and Arctic Ocean. These oceans are interconnected, but the distribution varies with the Pacific Ocean being the largest and the Arctic Ocean being the smallest.

What color algae are important in the formation of coral reefs?

User Avatar

Asked by Wiki User

Brown algae are important in the formation of coral reefs, as they provide a substrate for coral larvae to settle and grow. These algae also play a role in stabilizing the reef structure and providing food for various reef organisms.

What made the carbon cycle is leading to coral bleaching?

User Avatar

Asked by Wiki User

Elevated levels of carbon dioxide in the atmosphere are causing ocean temperatures to rise and oceans to become more acidic. This leads to coral bleaching by putting stress on coral reefs, which rely on a delicate balance of temperature and acidity to survive. Additionally, coral bleaching can also be triggered by pollution, overfishing, and other human activities that disrupt the natural carbon cycle.

Can you use sea water for a reef aquarium?

User Avatar

Asked by Wiki User

Yes, you can use sea water for a reef aquarium, but it must be properly filtered and treated to remove impurities and chemicals that may harm your marine life. Some hobbyists collect and filter their own sea water, while others prefer to use commercially available artificial sea water mixes that closely mimic natural seawater. Make sure to carefully monitor water parameters to ensure a healthy environment for your reef inhabitants.

Is a rock called shale formed from the skeletons of the ancient coral animals?

User Avatar

Asked by Wiki User

No, shale is a type of sedimentary rock formed from the accumulation of silt and clay particles. It is not formed from the skeletons of ancient coral animals, which are typically preserved in rocks such as limestone.

What rock began as coral?

User Avatar

Asked by Wiki User

Limestone. Limestone is a sedimentary rock that forms from the accumulation of calcium carbonate material, often from the shells of marine organisms such as coral. Over time, through compaction and cementation, this accumulated material solidifies into limestone rock.
