In the case of a bird eating a worm, the worm is the prey. The bird is a predator.
The mother bird eats a worm and regurgitates the processed worm for the chicks to eat.
The bird's body digests it, and it serves to nourish the bird.

every animal is important. Because all animals are part of the food chain, so if 1 kind of creature dies out it would affect the others in a bad way as they couldn't eat. E.g. bird eats worm, wolf eats bird. if the worm dies out the bird couldn't eat so the bird would also die out which means the wolf wouldn't have anything to eat leading that too to die out.

The second trophic level in a food chain is typically occupied by primary consumers, which are organisms that eat producers. In this case, the worm that eats the potato would be the primary consumer and thus occupy the second trophic level. The potato represents the first trophic level as a producer, while the bird and the fox occupy higher levels as secondary and tertiary consumers, respectively.
