Symbiosis

By Hannah Carhart

Description

Symbiosis is the interaction of two different animals living in the same area. The three types of this are mutualism, commensalism, and parasitism. Mutualism is when both animals benefit from the interaction. When one animal is helped but the other animal is unaffected, that is commensalism. Parasitism is when one animal is helped, but the other animal is harmed.

Mutualism

This is a form of mutualism because is an oxpecker and the zebra benefit. The oxpecker picks off the bugs, its form of food. The zebra benefits by having a pest control. The oxpecker can also warn the zebra by screaming a warning informing the zebra of danger.

Mutualism

Bees and flowers are another form of mutualism. The bees get food from the flower's nectar benefiting the bees. While eating the nectar, some of the flowers pollen rubs off on the bees. This helps to pollinate the flowers because when the bees travel to other flowers the pollen rubs off on them benefiting the flowers.

Commensalism

An example of commensalism is barnacles and whales. The barnacles attach themselves to whales where food is available. This benefits the barnacles. The whale is unharmed by this relationship.

Commensalism

Clownfish and anemone are another example of commensalism. The clownfish hide in the tentacles of anemone for protection of predators. This helps the clownfish, but doesn't help or harm the anemone.

Parasitism

The most famous example of parasitism is the dog and flea. The flea attaches itself to the dog and sucks its blood. This helps the flea because it gets food from the dog, but this harms the dog. The dog loses its blood and bothered.
