rafflesia flower and carrion flies relationship questions

Like all species of the rafflesia, the rafflesia arnoldii must use its host vine, the pollinated by bees like most flowers, the rafflesia is pollinated by carrion flies. Explain the probable relationship between the giant Rafflesia flower, which smells like rotting meat, and the carrion flies that buzz around it. (Hint: Carrion means Use this graph to answer the questions that follow. 9. What is the carrying. prey, certain symbiotic relationships, and coevolution. Competition . so well with the goldenrod flower that all it has to do is wait for its next . the following questions: Which animals in this . Rafflesia and carrion flies is a symbiotic mutualism.

The flowers open only rarely and then only for about five days. The flowers offer no reward to the flies, who are fooled into looking for food or a place to lay eggs. The distinctive projections on top of the disk in the center of the flower may help to radiate heat and spread the carrion odor. Rafflesia and its Relatives There are 13 species of Rafflesia living in southeast Asia.

These differ in size, coloration, and the number of various flower parts. The closest relatives of Rafflesia are Rhizanthes and Sapria, each with two species.

These are also Asian parasitic plants with smaller but equally bizarre flowers. Description Rafflesia arnoldii is a parasitic plant, without roots or leaves. The main body of the plant resides inside the host plant. The only visible parts are the flowers, which burst through the host plant's bark as compact buds, and later the fruits. The flowers are up to 1 m in diameter, and their flesh is reddish-brown with white spots. Each flower is either male or female and consists of five lobes inserted on a cup-like structure.

In the centre of the cup is a column with a disk. The anthers male parts or styles female parts are situated underneath the disk. The fruits are berries with minute seeds. It is likely that only damaged roots or stems of a new host can be infected by seedlings of Rafflesia. The foetid smell of the flowers attracts carrion-flies of the genera Lucilia and Sarcophaga.

The pollen adheres to the backs of the flies, which do not seem to receive any reward from the plant. Two varieties are known, the more common being R. The main difference between the two is that the central disk or ramenta is partly missing at the base of the central column in R. A race for discovery The first botanist to find a specimen of a Rafflesia was the French explorer Louis Auguste Deschamps He was a member of a French scientific expedition to Asia and the Pacific.

During the expedition he spent three years on Java, where in he collected a specimen of what is now known as R. When a bird eats a worm, the worm is prey and the bird is the predator.

Predators have a wide variety of methods and abilities of doing so.

The cheetah, for example, is able to run very quickly to catch its prey. Other predators, such as the goldenrod spider, shown in figure 1, ambush their prey. The goldenrod spider blends in so well with the goldenrod flower that all it has to do is wait for its next insect meal to arrive.

Prey are able to run away, stay in groups. Some prey are poisonous. They may advertise their poison with bright colors to warn predators to stay away. The fire salamander, shown in figure 2, sprays a poison that burns.

Predators quickly learn to recognize its warning coloration. Many animals run away from predators. Prairie dogs run to their underground burrows then a predator approaches. Many small fish, such as anchovies, swim in groups called schools.

Antelopes and buffaloes say in herds. All the eyes, ears, and noses of the individuals in the group are watching, listening, and smelling for predators. This behavior increases the likelihood of spotting a potential predator. A rabbit often freezes so that its natural color blends into a background or shrubs or grass.

Blending in with the background is called camouflage. Many animals mimic twigs, leaves, stones, bark, or other materials in their environment.

One insect, called a walking stick, looks just like a twig. Some walking sticks even sway a bit, as though a breeze were blowing.

Some animals defend themselves with chemicals. The skunk and the bombardier beetle both spray predators with irritating chemicals.

Bees, ants, and wasps inject a powerful acid into their attackers. The skin of both the poison arrow frog and a bird called de hooded pitohui contains a deadly toxin. Any predator that eats, or tries to eat, one of these animals will likely die.

What is the probable relationship between the giant rafflesia flower and the carrion flie?

Their chemical weapons are often advertised by warning colors. Predators will avoid any animal that has the color and patters they associate with pain, illness, or unpleasant experiences. The most common warning colors are bright shades of red, yellow, orange, black and white. Symbiosis Some species have very close interactions with other species.

Symbiosis is a close, long-term association between two or more species. The individuals in a symbiotic relationship can benefit from, be unaffected by, or be harmed by the relationship.

types of interactions

Often, one species lives in or on the other species. The thousands of symbiotic relationships in nature are often classified into three groups: For example, you and a species of bacteria that lives in your intestines benefic each other! The bacteria get food from you, and you get vitamins that the bacteria produce. Mutualism also occurs between some corals and the algae living inside those corals. In this relationship, a coral receives the extra food that the algae make by photosynthesis.

In turn, these algae also receive a place to live. These algae also receive some nutrients from the coral. Both organisms benefit from its relationship. One example of commensalism is the relationship between sharks and smaller fish called remoras. The remoras benefit from this relationship, while sharks are unaffected.
