BBC - GCSE Bitesize: Parasitism and mutualism
Symbiotic relationships are very important in nature and happen all around us. Symbiosis Leeches and Humans • Leeches are worms that suck blood from. One animal will benefits from the other aninaml that animal which lives off the other benefits from that animal or could suffers. A tapeworm and a human are. In other words, this is a one-sided symbiotic relationship. Example: Tapeworms Example: Dogs and humans have enjoyed a mutualistic symbiosis for.

Horse and humans are one example. The horse receives shelter, food and care from the human, while the horse is used for many jobs including transportation, hauling loads and in some cases, food.
Parasitism and mutualism
The ants feed on insects that are found on the tree, which in turn protects the tree from harmful predators. The tree is unharmed by the ants. The shrimp is almost blind leaving it vulnerable to predators when above ground. In case of danger the goby fish touches the shrimp with its tail to warn it. When that happens both the shrimp and goby fish quickly retract into the burrow. The burrs usually do not harm the cow, but the cow does not receive any benefit, either. The fleas suck blood from the skin of their host.
The fleas may cause blood loss, irritation and spread diseases over a period of time. After a period of time, the eggs hatch and the wasp larvae feed on the caterpillar from the inside out. The caterpillar eventually dies. The epiphytes receive a better location for collecting water and sunlight. The larger plant does not benefit in anyway. They hunt prey that live in the treetops of the rainforest.
They kill the prey by squeezing their bodies with their sharp talons. It will eat almost any insect, including its own young.

A “Mutualistic” Relationship between Parasite and Human: sel by Allyson Panton on Prezi
Click to see a detailed image There are three different types of symbiotic relationships, these include: An example of mutualism is the relationship between bees and flowering plants. Both organisms benefit in the relationship, the bee derives nectar and pollen from the plant while the plant becomes cross fertilised by the bees.Body Invaders - National Geographic

The relationship between the barnacles and the whale is an example of commensalism, where the barnacles benefit by being transported to food rich regions of the ocean while the whale is not harmed in any way in this relationship. Epiphytes are plants that grow on other plants in a non-parasitic relationship. Although an epiphyte derives its moisture and nutrients independently of its host it benefits by been high above the ground out of reach of herbivores and where there is more sunlight.
The host plant does not benefit nor is it harmed.
This relationship also is an example of commensalism. Another type of relationship is known as a predator-prey relationship. Simply put, a predator is an organism that eats another organism. The organism being eaten is the prey while the organism eating the other is the predator. For example, a dragonfly will eat flies and therefore the dragonfly is the predator while the fly is the prey.
Tapeworm and cow
This predator-prey relationship does not only apply to animals it can also apply to plants such as when a grasshopper eats grass, the grasshopper is the predator while the prey is the grass. Predator-prey relationships evolve over time, where the predator evolves all that is needed to successfully its prey. This may include camouflage, speed or bigger jaws.

Ants collect the seeds in their nests for the sugar. While in the ant's nest the seeds are safe from bushfires. This relationship evolved over thousands of years and is an example of 2 A tapeworm lives in the intestinal tract of humans.
