Which is a characteristic of animals that are in the same food web?

The characteristic that all animals in the same food web have in common is that they are consumers.

Explanation:

In food webs - also called food chains - there is a relationship between the food of living organisms that belong to an ecosystem, with some organisms serving to feed others.

The producers are the plants, capable of producing their own nutrients, so they are called autotrophs. From there, in the following links of the chain, there are the consumer or heterotrophic organisms (animals).

Consumers can be herbivores, or primary consumers, followed by carnivores, or secondary, tertiary and even quaternary consumers. The characteristic that includes animals in a food web is that they are all consumers, or heterotrophs.
