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. The fly is attracted by the "carrion " smell of the Rafflessia flowers, it carries the pollen on its body as it What is a relationship between a giant rafflesia and carrion flies? . Probability is used to answer questions in the category of Statistics. What is the relationship between the giant Rafflesia flower which smells like rotten meat and carrion flies -
Despite the use of DNA sequences, this riddle has proven difficult to solve. The problem is confounded by drastic reduction of the chloroplast DNA in Rafflesia and the transfer of some genes from the host plant directly into the genome of the parasite.
It was not until that a definitive study in the journal Science reported the findings of botanist Charles Davis of Harvard University and his colleagues. Rafflesia and its closest relatives, Rhizanthes and Sapria are nested squarely within a large flowering plant group with over 6, species known as the Euphorbiaceae, the euphorbs or spurges. This group contains some familiar plants, including the poinsettia, the rubber tree, the castor bean and the cassava, or yuca root.
What is striking about this discovery is that related plants in the Euphorbiaceae such as Ditaxis have small or even tiny flowers, which implies an astounding rate of increase in flower size along the line leading to Rafflesia. The remarkable size of these smelly giants may help lure pollinating flies to their blossoms by better mimicking decaying animals on the forest floor.
The World's Largest Flower Rafflesia arnoldii produces the largest known individual flowers, nearly three feet one meter across and weighing up to 15 pounds 7 kilograms.
Successful pollination is rare, however, because Rafflesia populations are few and far between. 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. 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.
What is the probable relationship between the giant rafflesia flower and the carrion flie?
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.How to draw Rafflesia Arnoldii
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. 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. 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.
types of interactions
The organism that benefits is called the parasite. The organism that is harmed is called the host. The parasite gets nourishment from its hots while the host is weakened. Sometimes, a host dies. This figures shows a bright green caterpillar called a tomato hornworm. A female was laid tiny eggs on the caterpillar. The young wasps will actually eat the caterpillar alive! In a short time, the caterpillar will be almost completely eaten and will die.

When that happens, the adult wasps will fly away. In this example of parasitism, the host dies. Most parasites, however, do not kill their hosts. If a parasite were to kill its host, the parasite would have to find a new host.
Coevolution Relationships between organisms change over time. Interactions can also change the organisms themselves. When a long-term change takes place in two species because of their close interactions with one another, the change is called coevolution. The ant and the acacia tree have a mutualistic relationship. The ants protect the tree by attacking other organisms that come near the tree.
The tree has special structures that make food for the ants. The ants and the acacia tree may have coevolved through interactions between the two species. Coevolution can take place between any organisms that live close together. But chances happen over a very long period of time. Pollination is necessary for reproduction in most plants.
Flowers have changes over millions of years to attract pollinators. Pollinators such as bees, bats, and hummingbirds can be attracted to a flower because of its color, odor, or nectar.
