Similar to how autotrophs store energy as starch, humans store excess energy derived from food in the form of glycogen. Both starch and glycogen serve as internal energy reserves that can be accessed when the organism requires additional energy.
How does the storage of energy in the form of glycogen in humans compare to the storage of starch in autotrophic organisms?

The storage of energy in humans as glycogen and in autotrophic organisms as starch exhibits similarities and differences. Both glycogen and starch serve as polysaccharide storage forms of glucose. However, glycogen is more highly branched than starch, allowing for rapid energy release during glucose breakdown. In humans, glycogen is stored primarily in the liver and muscles, providing a quick energy source. In autotrophic organisms like plants, starch is stored in chloroplasts and other plant tissues. The main distinction lies in the structural differences, influencing how these polysaccharides are utilized for energy storage and release in their respective organisms.
