Energy moves life. The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. Ecosystem is nothing but the interaction between the living and the non-living components of an area. Our ecosystem is maintained by the cycling energy and the nutrients obtained from different external sources.
At the first trophic level, the primary producers use solar energy to produce organic material through the process of photosynthesis. The primary consumers or the herbivores feed on these producers at the next trophic level while the secondary consumers or the carnivores at the next trophic level, feed on the herbivores and derive energy for their sustenance and growth. If large predators are present, they represent still higher trophic levels and they feed on these carnivores to get energy. Thus, the different plants and animal species are linked to one another through food chains and food webs.
All living things require energy in one form or another. Energy is required for the most complex metabolic pathways (often in the form of adenosine triphosphate or ATP), especially those responsible for building large molecules from smaller compounds. 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 input of energy.
It is important to understand how organisms acquire energy and how that energy is passed from one organism to another through food webs and their constituent food chains. Food webs illustrate how energy flows directionally through ecosystems, including how efficiently organisms acquire it, use it, and how much remains for use by other organisms of the food web.
Listen to the spherical cycle of Eternity, and integrate yourself into it. Everything is energy, and living in the Pure Energy will assure your place in the vast universe. The Cycle is a Cycle that flows a certain direction. Energies flow a certain way. You must listen to these natural energies and flow with the universe’s sway.
