Calvin Willis, who was released from state custody Friday after DNA testing showed he didn't rape a 10-year-old girl, said he's thankful for his freedom but needs money to survive in society. I think I should be compensated, Willis said during a press conference at the Innocence Project New Orleans.
A lichen is not a single organism. Rather, it is a symbiosis between different organisms-a fungus and an alga or cyanobacterium. Cyanobacteria are sometimes still referred to as 'blue-green algae', though they are quite distinct from the algae.
Each lichen specie is one alga species plus one fungus. The alga, a microscopic green plant, makes the food for the duo, while the fungus, a non-green plant, gives the pair support and soaks up moisture.
