(Nicola Davies) 'Whale' (Nicola Davies) This book about the symbiotic relationship between a hermit crab, anemone and bristle worm could be a start point for. symbiosis. to practice, you can use the "test" feature, select "multiple choice" and "start with term" The bristle worm removing parasites from the hermit crab and eating the A close relationship of a fungus and an algae that benefits both. Hermit crabs and sea anemones have a symbiotic relationship, meaning they live in harmony together. It's a stable connection that sidesteps the typical prey and.

Each group must put one of the following headings onto the poster. You have 3 minutes to add as much detail to this poster as you can.
Repeat until back at first poster. Each group must take a turn to feedback to the whole group from the poster they started with. Symbiosis card sort Instructions 1. Print out following pages and cut into individual cards with a matching picture. Make three categories to place cards into; parasitism, mutualism, social behaviour. Read out statement 2. The bacteria get a constant source of moisture and food.
The bacteria get a stable habitat to live in temperature and pH. The bacteria break down cellulose. Without the bacteria the cow would not be able to break down the grass cell walls. Mr Fraser gives the dog food and water whenever it is needed. Oscar makes Mr Fraser very happy. Some species of shrimp live with a fish called a goby.

The shrimp digs a house by moving sand around. The goby lives in the house the shrimp digs out. The shrimp is blind and uses its feelers to check the goby is nearby. If the goby notices danger and retreats into the home the shrimp does too.
A hermit crab is able to carry an anemone on its back. The anemone is put there by the crab. The weight of the anemone makes it harder for the crab to move around. Food scraps from the crab can get to the anemone. The anemone will stop an octopus from eating the crab. A tick is a small invertebrate that can live on larger animals.
Here it feeds on blood from the organism. The blood is stored in an expandable pouch on the tick. The organism loses blood and may get an infection, eg Lyme disease in humans. Most will never get to breed.
They can get more food by working cooperatively. The colony will die if each type of ant does not do its job. Since the ants are closely related, similar genes will be passed on. Bodungo chimps are social animals. Chimps form close relationships with each other.
By being in a group they share food and resources. A young male is unlikely to become the most dominant male in the group. By living together as a large group the troop is likely to be successful and their genes will be passed on. It is caused by a protist. Mosquitoes carry protists for part of their lifecycle.
The mosquito transfers the protist when feeding on human blood. The protist needs both vectors to complete its lifecycle. Birds frequently live in trees.

They use parts of an old tree to make their nests. The bird gains an advantage of a home to live in. The tree gains little from the relationship, maybe some fertiliser. The bird does nothing to harm the tree. Types of symbiosis There are two basic types of symbiosis. Remember that symbiosis is the relationship between two organisms of different species that benefits one or both organisms: Decide which type of symbiosis is described in each sentence below.
A tick living on a dog. A bird building its nest in a tree. A hermit crab carrying a sea anemone on its back. A bristle worm living with the hermit crab. Head lice living on a human scalp. Mistletoe putting its roots into its host tree.
Ants and an acacia tree living together and both receiving benefit.
Bees and a flower. Bacteria living in the intestines of a cow to help it break down cellulose. A clownfish and a sea anemone. A sixth-year student and their pet. A rhino and a tick bird. Lichen — a composite organism of a fungus and an alga that benefits both. Cleaner fish eating parasites off of a grouper fish. Bacteria, Rhizobium, that live in nodules on plants roots and fix nitrogen, using energy from the plant, which the plant is able to then use.
You need to distinguish between mutualism and parasitism. Example of a branching key: Check it works with the various examples — possibly use the symbiosis worksheet. Why is it necessary for a parasite to keep its host alive? Explain how parasites and their hosts interact to maintain a stable relationship.
Describe the three ways that parasites can be transmitted. Describe, in general, the structure of most parasitic cycles. Many parasites have resistant larval forms incorporated into their life cycles.
Suggest a reason for this. Explain, in evolutionary terms, how most parasites have become host specific.

Describe the phenomenon of mutualism. Describe the relationships that exist between the following organisms: Both are selfish and only care about themselves. A prosecutor makes the following offer to each. If you confess and your accomplice remains silent I will drop all charges against you and use your testimony to ensure that your accomplice does serious time 10 years. Likewise, if your accomplice confesses while you remain silent, they will go free while you do the time 10 years.
If you wish to confess, you must tell me in the morning. This is surely the worst situation. Both get 7 years, so 14 in total!!
The solution becomes apparent when we look at the potential outcomes. If one person does not confess then they will either get 2 years or 10 years — an average of 6 years. If they do confess they will either get 0 years or 7 years — an average of 3.
So they choose to confess and implicate the other on that basis. But the outcome obtained when both confess is worse for each than the outcome they would have obtained had both remained silent. A common view is that the puzzle illustrates a conflict between individual and group rationality. It shows a choice between selfish behavio ur and socially desirable altruism. The following is the explanation assuming that Frank and Bob cannot communicate to each other.
Upon finding a new shell and moving in a worm asks if he can move in with him and he offers to keep the shell clean in return, to which the crab agrees. Next an anemone moves in with the promise to protect the crab and worm from enemies. Soon the three characters outgrow the shell and argue leading to them going their separate ways. However, a storm occurs and the worm finds a bigger shell to accommod Sharing a Shell starts with a crab searching for a new home as he has outgrown his current one.
However, a storm occurs and the worm finds a bigger shell to accommodate them all and they soon move back in together.
The book explores friendships and relationships, of how the characters can co-operate with each other to make a lovely place to live even though they are not the same species.
Sharing a Shell also highlights the importance of each character, as without each other they are lonely and the shell will be dirty, at risk and unable to move around. Children can then expand on this to see what jobs there are within the UK and the World over and how they assist the people who live there.
Sharing a Shell uses rhyme to tell the story, this allows for children to explore the world of rhyme and start to look at how to use it themselves in writing.
Also, the child can discover what makes words rhyme including the phonic sounds heard in the word.
