The trophic pyramid illustrates energy transfer within ecosystems, highlighting primary producers, consumers, and decomposers. Energy from the sun is stored as biomass, with only 10% transferred between trophic levels. Ecosystem changes, such as reduced sunlight or pesticide use, can impact the entire pyramid, emphasizing the interconnectedness of ecosystems and the importance of energy cycling.
