Symbiosis (from Greek σύν "together" and βίωσις "living") is close and often long-term interaction between two different biological species. In 1877 Albert Bernhard Frank used the word symbiosis (which previously had been used to depict people living together in community) to describe the mutualistic relationship in lichens. In 1879, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms."
The definition of symbiosis has varied among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to any type of persistent biological interaction (in other words mutualistic, commensalistic, or parasitic). After 130 years of debate, current biology and ecology textbooks now use the latter "de Bary" definition or an even broader definition (where symbiosis means all species interactions), with the restrictive definition no longer used (in other words, symbiosis means mutualism).
Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival. For example, many lichens consist of fungal and photosynthetic symbionts that cannot live on their own. Others are facultative (optional): they can, but do not have to live with the other organism.

Symbiosis is close and often long-term interaction between different biological species. The definition of symbiosis is controversial among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to all types of persistent biological interactions (i.e. mutualistic, commensalistic, or parasitic). In this video we show how you can simply visualize all three.

In this webisode Jonathan explores different types of symbiosis in the ocean, including mutualism, commensalism and parasitism, and how animals use it for survival. This is an HD re-release of a season 3 episode. ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe!

With so many organisms on Earth, living things are bound to interact with one another. Symbiosis is a close relationship between two species. One type of interaction between two species is called mutualism. An example of mutualism exists between honey bees and flowers. Flowers provide nectar to the bees. The bees use the sugar rich liquid to make honey. As the bees fly from flower to flower tiny grains of pollen get stuck to the bee. The bee moves the pollen without even knowing it. The pollination is necessary for flowers to reproduce. In this relationship both species benefit. The bee gets nectar and the flower gets pollinated. Another relationship is called commensalism. This interaction takes place when sharks and remora live together. The remora use sucking disks on the...

One of the oldest examples of mutual symbiosis in nature is the relationship between protozoa and termites. There are fossil records of this relationship occurring over 100 million years ago making this form of mutual symbiosis between an animal and a microorganism the oldest we know of to date. A protozoa is a microorganism that exists very frequently in nature, and they are now known to be found in the digestive systems of termites. This is what gives termites their extraordinary ability to eat through wood. In return, the termite provides the protozoa with valuable nutrients that it needs to pe...

I wanna be your partner
I wanna be your friend
You never let me in to
Your own little world
You wanna be so secret
It's only for the show
Tear down your silly barriers
And let me know
How much more should I try
How much more will it take
How much more punishment
Can I tolerate
In your world lives a little girl
Who is longing for a life
For a life
I wanna kill your character
I want the real you
Fuck that fucking roleplay
And fuck your medicine
Schizophrenic alter egos
You hide behind your diagnosis
You think you have the sole right
To depression and despair
How much more should I try
How much more will it take
How much more punishment
Can I tolerate
If you only let her out
In your world lives a little girl
Who is longing for a life
If you only let her out
