Algae provide the lichen with food that the algae produces. The lichen provides shelter, water and minerals for the algae.
That the enzyme must be specific for one constituent of lichen, say a carbohydrate bond, so lichen probably needs many types of enzymes to preform catabolic reactions on it's many constituent parts.
No because lichin needs moisture to grow and there isn't moisture in a desert.
As much as the plant needs. The excess water is thrown out.
lichen a lichen is a producer that is actually composed of two different species, a fungus and an alga. the alga photosynthesizes, while the fungus absorbs nutrients from rocks and holds water. together they begin to break down the rock.

Lichen are a good pollution indicator because they get their water and minerals from rainwater and the atmosphere. This makest lichen extremely sensitive to the atmosphere. As a result very few lichen grow in or near large cities with heavy pollution.
A lichen is a hybrid of a fungus and an algae. In the arctic the lichen must be exceptionally sturdy. The algae providing the food through photosynthesis and the fungus extracts available water to forma symbiotic relationship.
That the enzyme must be specific for one constituent of lichen, say a carbohydrate bond, so lichen probably needs many types of enzymes to preform catabolic reactions on it's many constituent parts.
Wolf lichen, British soldier lichen, or Christmas lichen. These are a few of many.
No because lichin needs moisture to grow and there isn't moisture in a desert.
how ever much it needs
None
Lichen EDIT: Lichen is not so much an example of biological weathering, as a cause. When Lichen grows on rocks it releases chemicals which dissolve the rock. This can be seen in rocks which appear to be covered in flakes of rock.

it needs a bit of water (10ml)
As much as it needs.
