Question

The first link in a food chain can be which of the following? Select all that apply. bacteria plants autotrophs heterotrophs carnivores​

Answer 1

The first link in a food chain can be bacteria and plants, which are autotrophs. Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis. Heterotrophs, which are organisms that consume other organisms, including carnivores, cannot be the first link in a food chain because they require a source of food to survive.
