Why Ecosystems require energy to function. Where does this energy come from Where does it go or How does it flow?

Ecosystems require energy to function because it drives the processes that sustain life, including growth, reproduction, and nutrient cycling. This energy primarily comes from the sun, which is harnessed by plants through photosynthesis, converting solar energy into chemical energy stored in organic matter. Energy flows through the ecosystem as it moves from producers to consumers and decomposers, with a significant amount lost as heat at each trophic level according to the laws of thermodynamics. Ultimately, this flow of energy supports the complex interactions and dynamics within ecosystems.
