Identify the symbiosis


                Symbiosis is the relationship between two different organisms living together. A Host usually the Larger  of the 2 organisms, And a Symbiont is usually the smaller member. The three symbiotic relationships are parasitism, mutualism, and commensalism. Parasitism is the relationship where the symbiont lives on the host. Mutualism Is a relationship between the host and a symbiont, where both organisms benefit and neither is harmed.  Commencilism is a class of relationship between two organisms where one organism benefits but the other is neutral.

photosynthesis

Lichens make their own food from their photosynthetic parts and by absorbing minerals from the environment. The fungus lives in a symbiotic relation with the algae. The fungus benefits from the algae or cyanobacteria because they produce food by photosynthesis. The algae or cyanobacteria benefit by being protected from the environment by the filaments of the fungus, which also gather moisture and nutrients from the environment, and provide an anchor to it.

            The alga on the plant represents mutualism. This means it does not harm the log. This is a relationship that one harms and the other is not affected. The Fungus grows on the plant to live and become bigger. As I see on my trees, I can see that the same type of algae is growing there to. This alga on the plant is called a niche. Which means a role or meaning taken by an organism. 

Identify The Symbiosis

The fungus is growing on the log, and it shows mutuilism because the fungus on the log is befitting by growing from the log and the log is also benefiting. They are both not harmed. This is my own picture I took of another example of mutuallism.

Identify the Symbiosis by Faith

        In this photos the Lichens on the piece of wood are helping the wood. Lichens are made up of alga or a cyanobacterium that lives within the tissues of a fungus. When plants go through photosynthesis the cyanobacterium supplies energy to the fungus or itself. The Lichens gain from the wood because working together they make energy and protein so that the wood can live. The wood is giving the lichen a place to live so both the lichens and the piece of wood benefit so the symbiosis is mutualism. 

Here is a photo of the wood.

Identify the Symbiosis

The log and fungus are in symbiosis because the fungus benefits and the log is not affected. The fungus is a lichen, because niche's are alleges and funguses. So... yeah... SCIENCE! The fungus get's energy and a habitat from the log, and the log isn't harmed, nor benefited in anyway, so the log is like "AYE, Buddy! I heard you need a place to stay, I got yo back homie!" Then the fungus is like "omg dude, you're so awesome and stuff! Hope you know I need energy from you too." Then the log is totally like "It's all cool brah, I ain't even mad." Then they both end up dead.

Identify the Symbiosis

Lichens and Logs.

 Before i tell you witch symbiosis this relationship is i am going to tell you what lichen is, does, and where it grows.

Lichen grows on trees, logs, rocks, and more. There are about 20,000 species of lichen that are known. It is estimated that 6% of all land on Earth is covered in Lichen. Lichens grow in different colors, shapes, and sizes. Lichen can survive in extreme conditions such has the arctic tundra, desserts, rock coasts, or toxic slag heaps. they can even grow inside rocks.

Now that you know a little more about lichen i will now tell you the symbiosis relationship between a log and lichen. The symbiosis relationship between a log and lichen is called Mutualism. Mutualism is when both organisms benefit from the relationship.
