What are the two principal types of connective tissue in a muscle? collagen and myofibrils myofibrils and elastin myofibrils and disks elastin and collagen?

The two principal types of connective tissue in a muscle are collagen and myofibrils. The entire muscle is wrapped in collagen to form a fascicle. Looking at one muscle fiber, you will see that almost the entire cross section of the muscle fiber is composed of long, cylindrical strands of proteins called myofibrils. 

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
