Would food be biotic or abiotic in the ecosystem?? Please help quick

Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.

So to answer your question,

Biotic: plants and other prey (animals)

Abiotic: water, soil,
