 Description
 In this task, the otter's habitat, the "freshwater" ecosystem, is investigated in more detail. The producers, decomposers and consumers living there are learned about by summarizing them in a clear diagram. But not only the freshwater is examined, but also the "forest" ecosystem and the biotopic and biocenic environmental factors found in it.
