Symbiosis. Sometimes it is a mutualism; sometimes it is a parasitism.
No. The alga and the fungus that make up a particular lichen exist in a true symbiotic relationship where neither can exist without the other. Generally, the fungi absorb water that passes on to the algae to be used in photosynthesis to create a carbohydrate food for both. So both organisms benefit from the relationship.

Okay. Firstable, there are 3 kinds of symbiosis : parasitism, mutualism and commensalism. If u want to understand it ezly. Paratism=one of them good others are super-bad. e.g.)tapeworms, lampreys whatever... mutualism=both of them happy e.g.)alga+fungus&linchens, birds commensalism=one of them is happy others not happy not sad (so so) the answer 4 ur Q is The association of an alga and a fungus in linchens is another example of mutualism. the nonphotosynthetic fungus provides moisture and support for the alga, which in turn synthesizes food for the fungus and itself. did u like it? i hope u did.
A lichen is not a single organism; it is a stable symbiotic association between a fungus and algae and/or cyan bacteria. Symbiotic means any two life form that can only exist with the two life forms are together. There are many examples of this in the plant world, where a plant only have one pollinator and the pollinator only feeds on that plant. Like all fungi, lichen fungi require carbon as a food source; this is provided by their symbiotic algae and/or cyan bacteria, that are photosynthetic. The lichen symbiosis is thought to be a mutualism, since both the fungi and the photosynthetic partners, called photobionts, benefit.

Mushrooms are fungi that are unattached, they simply grow on decomposing material or poo. Lichens attach to trees or stones. Freddy Fungi was lichen Alice Algae. Two or more kingdoms are involved in a lichen.
Mutualism between fungus and algae, forming lichens, allows both partners to benefit by sharing resources and increasing their overall fitness. The algae perform photosynthesis and provide the fungus with sugars, while the fungus provides a protected environment and absorbs water and nutrients for the algae. This symbiotic relationship enables lichens to thrive in a variety of harsh environments where neither partner could survive alone.

In Object-oriented design, association is a relation between two objects, for example, Car & Wheel have an association (that is, car contains wheels), Toolbar & Button have an association (that is, toolbar is composed of buttons), a Student is associated to Course (that is, a student can study a course). It can be strong association or weak association. If A is strongly associated to B then A cannot exist without B. In implementation terms, object A would be composed of object B & without creating B, creation of A is not possible. For example, a Toolbar cannot be created without creating a Button. If A is weakly associated to B then A can exist without B. For example, a Student can exist without the exitence of Course.

The fungus Candida albicans can act as a facultative parasite, meaning it can exist as a commensal organism in the human body but can also cause infections, particularly in immunocompromised individuals.
