The sun
The primary producers, such as plants or algae, would begin the flow of energy through a desert food web by converting sunlight into chemical energy through photosynthesis. These primary producers are then consumed by herbivores, which are subsequently consumed by predators, leading to the flow of energy through the food web.

There are several different factors that control the primary productivity of energy and biomass flow. Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories. Accordingly, the energy flow is also called calorific flow. In the study of energy flow, ecologists try to quantify the importance of different species and feeding relationships.

The flow of energy occurs from the sun in photosynthetic organisms. Another examples is a food chain with the flow of energy from through organisms from a producer. The flow of materials describes the movement of materials or components.
