map concept 1 illustrates the flow of energy in ecosystems, including how energy is transferred between producers, consumers, and decomposers. map concept 2 shows the value of biodiversity and the factors threatening it, focusing on species interactions and ecosystem services. map concept 3 presents the biosphere’s global ecological processes, including nutrient cycles and human impacts on the environment. Each concept map illustrates a different but interconnected aspect of the biosphere. In Chapter 4, we explore how energy is the driving force behind ecosystem function. Energy flows from producers (plants and algae) to consumers (herbivores and carnivores) and eventually decomposers, sustaining life and maintaining ecosystem balance. This energy flow is crucial for understanding the dynamics described in Chapters 7 and 8. In Chapter 7, the focus shifts to biodiversity, which depends on the energy and nutrient availability in ecosystems. Biodiversity increases the resilien...
