What is a water ecosystem

Water ecosystem

After all, ecosystems are complex, because they not only contain linear impact chains, but also impact networks and cycles that interact strongly with one another. If one component changes (e.g. lower solar radiation), this has an impact on the entire ecosystem. This characteristic also illustrates why the dynamism of an ecosystem is so great and has such a strong impact.

Each ecosystem is characterized by its own material cycle. Even between ecosystems of the same species, such as two rivers, there are many differences. This is mainly due to the different abiotic factors (i.e. wind, sun, soil, ...). There are three types of living beings in a material cycle: producers, consumers and destructors. Producers are representatives of the plant world such as algae, which through their growth produce organic material (e.g. their leaves) and oxygen. This organic material is eaten by animals, the primary consumers. Primary consumers are animals that mainly eat plants, e.g. snails, small fish and insects.

Secondary consumers in bodies of water are, in turn, carnivores such as fish, storks and turtles. If consumers or producers die, they are broken down by the destructors. In water bodies these are mostly bacteria that can get by with very little oxygen. They transform the organic material into inorganic substances that producers need for food. Because producers, consumers and destructors depend on one another for survival, a stable system of give and take develops.
