relationship between rafflesia flower and carrion flies

What is the relationship between the giant Rafflesia flower which smells like rotten meat and 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. What is a Phylogenetic Relationship? These bizarre organisms produce the world's largest flowers. (seed bearing), and may be pollinated by “bluebottle” carrion flies attracted by the color and the smell of “tainted beef.” Successful pollination is rare, however, because Rafflesia populations are few and far between.

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.

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

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. The magnificent flowers of Rafflesia arnoldii have become a symbol of Borneo. Tragically, Rafflesia and its relatives are now all threatened with extinction from destruction of their rainforest habitats. 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. 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.

types of interactions

Pollinators such as bees, bats, and hummingbirds can be attracted to a flower because of its color, odor, or nectar. Flowers pollinated by hummingbirds make nectar with the right amount of sugar for the bird.

Hummingbirds have long beaks, which help the drink the nectar. Some bats changed over time to have long, thin tongues and noses to help them reach the nectar in flowers. As the bat feeds on the nectar, its nose becomes covered with pollen.

The next flower it eats from will be pollinated with the pollen it is gathering from the first flower. The long nose helps it to feed and also makes it a better pollinator. Because flowers and their pollinators have interacted so closely over millions of years, there are many examples of coevolution between them.

Assessment Using key Terms 1. In your own words, write a definition for the term carrying capacity. Carrying capacity is the maximum number of individuals that can live in an environment. Use each of the following terms in a separate sentence: Mutualism is when two organisms that are interacting both benefit from the relationship.

Commensalism is when one organism is helped and the other is not affected.

Parasitism is when one organism is helped and the other is harmed by the relationship. Understanding Key Ideas 3. Which of the following is NOT a prey adaptation a. Identify two things organisms compete with one another for.

types of interactions

Briefly describe one example of predator-prey relationship. Identify the predator and the prey. When a cat eats a mouse, the cat is the predator and the mouse is the prey. Compare coevolution with symbiosis Sample answer: Coevolution happens when a symbiotic relationship occurs over a very long period of time and changes the structure or behavior of the organisms involved in the relationship.

However, symbiosis does not always cause a change in the structure or behavior of an organism. Explain the probable relationship between the giant Rafflesia flower, which smells like rotting meat, and the carrion flies that buzz around it.

The relationship between the flower and the flies is probably coevolution brought about by symbiosis.
