Which way does energy flow?
Subsequently, one may also ask, which way does energy flow in a food web?
Within the food chain energy can be passed and transferred from one organism to another. Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers.
Similarly, you may ask, how does energy flow?
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
