What is the difference between a food chain and a food web?

In an ecosystem, a food chain shows the linear transfer of energy and nutrients from one organism to another. It follows a single path of energy transfer. On the other hand, a food web is a more complex system that depicts the multiple interconnected food chains within an ecosystem. It represents the overlapping and interconnecting food chains, showing the various paths of energy flow. While a food chain simplifies the flow of energy, a food web provides a more comprehensive understanding of the intricate relationships between different organisms in an ecosystem.

These concepts are important in understanding the dynamics of ecological systems.
