That’s basically what freshwater tertiary consumers are. Secondary Consumers - Fish (Carp) Primary Consumers - Snails Producers - Earthworms, fungus, bacteria. The micro consumers of rivers are the herbivores, predators and parasites. The surfaces of rivers and streams are interfaces for a host of chemical exchanges with the atmosphere and biosphere. Rivers can be wide and deep, and many empty into larger bodies of waters such as oceans or lakes. However, ... secondary consumers (Thackeray et al., 2010). This is known as a lotic (flowing water) system. The South and Central American rivers and streams contain the greatest number of species on Earth, with recent estimates ranging as high as 8000 and 25% of global fish species richness. They are secondary consumers and … Animals are consumers. Most frogs have teeth, while toads do not. For instance, carbon dioxide outgassing from rivers is estimated to be equivalent to one-fifth of combined emissions from fossil fuel combustion and cement production. Next, we’ll learn about the freshwater tertiary consumer, the Eurasian otter. Aquatic macroinvertebrates serve multiple functions in freshwater ecosystems. Another example would be a northern Pike eating a blue gill wwhich eats algae which also has photosynthesis. These conditions differ greatly between small headwater streams and the mouths of such great rivers such as the Mississippi and the Amazon. 1 Answer/Comment.
