Chapter 2. Energy Pyramids

2.1 Energy Pyramids

Introduction:

The laws of thermodynamics describe the transfer of energy in systems. The first law states that energy is conserved in the system and cannot be created nor destroyed. The second law states that with each transfer, some energy will be lost or dissipated as a less usable form. As energy moves through the trophic levels of an ecosystem, for example, its availability diminishes as it travels from producer to each level of consumer. With each movement up the pyramid, a common rule of thumb is that roughly 90% of the available energy is dissipated.
