Energy does not cycle through an ecosystem.This is because energy enters an ecosystem through photosynthesis as it changes to chemical energy.This is then used to fuel metablic activities

Question

Quizplus · Accepted Answer

Energy enters the ecosystem as sunlight and is converted to chemical energy through photosynthesis in producers. This energy is then transferred to consumers when they eat the producers or other consumers. Decomposers, such as bacteria and fungi, break down dead organic matter and release energy back into the ecosystem. However, all organisms release excess energy as metabolic heat, and this energy is not cycled back into the ecosystem. Therefore, energy does not cycle through the ecosystem, but rather flows in a one-way direction from producers to consumers to decomposers, with excess energy being lost as metabolic heat.
