The slow metabolism and excretion of DDT lead to severe ecological consequences, including population declines in affected carnivores, as trace amounts in primary producers like plankton become exponentially concentrated as they ascend the food chain.

(Since the water content of the two is not the same, the conversion efficiency is somewhat less than the apparent 50%.) Nonetheless, the loss of energy as it passes from producers to primary consumers explains, for example, why it costs more to buy a pound of beefsteak than a pound of corn.

Energy is required by most complex metabolic pathways (often in the form of adenosine triphosphate, ATP), especially those responsible for building large molecules from smaller compounds, and life itself is an energy-driven process. Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.

It emphasizes the need for effective pest control without harming beneficial insects or humans. Additionally, it discusses insect growth regulators that affect larval stages and their potential harm to non-target organisms. The text advocates for innovative insecticides to address insecticide resistance and maintain ecological balance.

The producers pass their energy to the various trophic levels of consumers. At the base of detrital food webs are the decomposers, which pass their energy to a variety of other consumers. Detrital food webs are important for the health of many grazing food webs because they eliminate dead and decaying organic material, clearing space for new organisms.

Organisms in an ecosystem acquire energy in a variety of ways, which is transferred between trophic levels as the energy flows from the bottom to the top of the food web, with energy being lost at each transfer.
