What are 5 examples of parasitism?
Examples of parasites include mosquitoes, mistletoe, roundworms, all viruses, ticks, and the protozoan that causes malaria.
What is an example of predation in the coral reef?
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. In extreme cases, entire reefs can be devastated if predator populations become too high.
What is an example of a symbiotic relationship in a coral reef?
The symbiotic relationship between an anemone (Heteractis magnifica) and a clownfish (Amphiron ocellaris) is a classic example of two organisms benefiting the other; the anemone provides the clownfish with protection and shelter, while the clownfish provides the anemone nutrients in the form of waste while also scaring …
Are corals parasitic?
of corals are parasites and mutualists.
What are 2 examples of parasitism?
A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles.
What are 4 examples of parasitism?
Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes.
What can kill coral?
Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world.
Why is coral so hard?
Hard corals—including such species as brain coral and elkhorn coral—create skeletons out of calcium carbonate (also known as limestone), a hard substance that eventually becomes rock. Hard corals are hermatypes, or reef-building corals, and need tiny algae called zooxanthellae (pronounced zo-zan-THEL-ee) to survive.
How do corals produce oxygen?
Most corals, like other cnidarians, contain a symbiotic algae called zooxanthellae, within their gastrodermal cells. In return, the algae produce oxygen and help the coral to remove wastes.
How do corals get their Colour?
Because photosynthesis requires sunlight, most reef-building corals live in clear, shallow waters that are penetrated by sunlight. The algae also give a coral its color; coral polyps are actually transparent, so the color of the algae inside the polyps show through.
Is coral symbiotic?
Symbiosis is deceptively easy to define: two or more organisms live together in a long-term association. Coral, the partnership between an animal from the Anthozoa group and a microbial alga called Symbiodinium, is an archetypal model of symbiosis.
How do coral reefs benefit humans?
Benefits of coral reef ecosystems Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.
Which is an example of parasitism on coral reefs?
A famous example of parasitism on reefs is the tongue-eating louse of the species Cymothoa exigua. Also referred to as “fish lice”, this marine isopod is known to remove the tongue of fish hosts by extracting blood, and then to replace the organ by acting as the fish’s new tongue!
Which is an example of mutualism in coral reefs?
There are numerous examples of mutualism on coral reefs. One is the relationship that cleaner shrimp (Lysmata anboinensis) have with many species of larger ‘client’ fish, who come to the shrimp to be cleaned of parasites and dead skin, which the shrimp then eat¹.
What kind of interactions do fish have with coral reefs?
On coral reefs, parasitic interactions are incredibly common and varied, as reef fish are excellent and abundant hosts. Because of this diversity, this post will focus on several different examples of the many kinds of parasitic mechanisms found on reefs.
Why are there so many diseases in the coral reef?
Major Reef-building Coral Diseases – ” Coral diseases and syndromes generally occur in response to biotic stresses such as bacteria, fungi and viruses, and/or abiotic stresses such as increased sea water temperatures, ultraviolet radiation, sedimentation and pollutants. One type of stress may exacerbate the other (Santavy and Peters, 1997).
