The ecological model would be the food web.
A food web is an illustration that shows feeding relationships among the various species of living organisms living in a particular ecosystem.
A food web is different from a food chain because a food web shows networks of feeding relationships while a food chain only shows linear feeding relationships among organisms in ecosystems. In other words, a food web is made of multiple food chains linked together.
A food chain shows linear feeding relationships between organisms but gives no room for organisms to share more than one relationship within the ecosystem.
A typical food web shows all the possible feeding relationships that organisms exhibit within the ecosystem. For example, many primary consumers depend on producers for their foods. A particular primary consumer in an ecosystem may be a source of food for several secondary consumers, and so on.
In other words, the ecological model of networks of feeding relationships among organisms in a community from producers to decomposers is known as the food web.
