Food Web – Definition, Trophic Levels, Types, and Example
2023年2月17日 · Organisms in food webs are grouped into four groups or trophic levels. They are: Producers or autotrophs make up the first trophic level of the food chain. They prepare their own food from sunlight, carbon dioxide, and water through photosynthesis. All other organisms in the ecosystem use them for food.
