Answer 1

a) green alga or cyanobacterium

b)The algae or cyanobacteria benefit their fungal partner by producing organic carbon compounds through photosynthesis. ... The prokaryotes belong to the Cyanobacteria, which are often called by their old name “bluegreen algae”. Bluegreen algae occur as symbionts only in about 8% of known lichens.

c) Mutualistic interactions are mutually beneficial species interactions. Plant-pollinator mutualisms are particularly important, and involve nearly 170,000 plant and 200,000 animal species. Mutualistic interactions, or mutualisms, are ubiquitous in nature.
