Symbiosis in lichens is the mutually helpful symbiotic relationship of greenalgae and/or blue-green algae(cyanobacteria) living among filaments of a fungus, forming lichen. The algaeor cyanobacteria benefit their fungalpartner by producing organic carbon compounds through photosynthesis
        
                    
             
        
        
        
The primary energy system to fuel cycling for 15 minutes is THE AEROBIC GLYCOLYSIS SYSTEM.
There are different energy systems for fueling different types of physical exercise, the type of system that is used depend on the duration of the physical exercise. The energy system that exist are anaerobic glycolysis, aerobic glycolysis, phosphagem system and fatty acid oxidation. The aerobic glycolysis energy system relies on the complete breakdown of glucose. The pyruvate which is the end product of glucose oxidation is further broken down to acetyl coA, which then enters into the citric acid cycle. The aerobic glycolysis energy system is used for physical exercises that last between three to twenty minutes.
