We can distinguish one global web from the other by locating the producers either on land or on water.

Explanation:

"Food web" is an ecological concept where it represents feeding relationships inside communities. It is the collection of interconnected food chains where the food energy is transferred from one species to the other. The food webs can be used to unfold the various patterns of energy transfer in aquatic and terrestrial ecosystems. That is locating the producers either on land or on water.
