The relationship between energy transfer and trophic levels is essential for understanding ecosystems. Energy flows from one trophic level to the next, beginning with producers (plants) that convert sunlight into energy. This energy is then passed to primary consumers (herbivores) and subsequently to higher trophic levels (carnivores). However, energy transfer is inefficient, typically allowing only 10% of energy to move up each level due to metabolic processes and heat loss. This concept is crucial for ecology, biodiversity, and conservation efforts.
