What term is used to refer to the many feeding relationships that are possible in an ecosystem

Food web

Explanation:

In an ecosystem, the series of organisms that are connected to each other by energy and nutrient flow is called the food chain. One organism in a food chain derives the nutrition and energy from the preceding organism of the chain. However, most of the linear food chains are interconnected to form food webs.

Food webs are interconnected food chains that occur in nature since organisms derive their nutrition from multiple sources. For example, a grasshopper can feed on grasses and grain both. A bird can derive its nutrition from a grasshopper or grain. Likewise, an owl can feed on mice or grasshoppers. These multiple feeding relationships lead to the existence of food webs.
