## The Interdependence of Ecosystems ### Pretest: The Interdependence of Ecosystems #### An ecological pyramid shows the transfer of energy. Which level will contain only 0.1% of the total energy obtained from the Sun? The image depicts a biomass (energy) pyramid that represents the distribution of energy across different trophic levels within an ecosystem. The pyramid has the following energy levels: - **Top Level:** 5 kcal (Hawk) - **Second Level from Top:** 50 kcal (Snakes) - **Third Level from Top:** 500 kcal (Mice/Rats) - **Base Level:** 5000 kcal (Plants) The pyramid illustrates that as energy is transferred from one trophic level to the next, a significant amount of energy is lost, primarily through metabolic processes and as heat. Each level receives only about 10% of the energy from the level directly below it. Thus, the hawk at the top represents the apex predator, containing only 0.1% of the energy initially captured by the producers (plants) at the base level. Biomass (energy) pyramids are fundamental in understanding the efficiency of energy transfer within an ecosystem and highlight the importance of primary producers in supporting the entire food web.
