Freshwater Food Chain If we simplify who's eating who, we get a direct pathway. Another These form the base of the food chain and are called primary producers because they produce their own food from sunlight through photosynthesis. There are organisms, like bacteria and fungi, that are decomposers: they feed on non-living organic matter and are a necessary step to cycle energy.

We also have parasites, like leeches, that feed on an animal, harming it in the process. Because of its stable increment in the food web, δ 15 N is considered to be a good indicator of TL and food chain length.
