Energy flow refers to the transfer of energy through a system, such as an ecosystem or a food chain. It is the movement of energy from one organism to another within an ecosystem. The sun is the primary source of energy for most ecosystems, and this energy is captured by plants through photosynthesis. The energy is then transferred from plants to herbivores, and then to carnivores, and so on, creating a flow of energy through the ecosystem.

Study Guide
Here are some key points to focus on when studying energy flow:
Understand the role of primary producers in capturing and converting energy.
Learn about the different types of consumers and their roles in the transfer of energy.
