Final answer:

The incorrect statement is that amoebas are the primary producers in both freshwater and saltwater ecosystems. The primary producers in freshwater biomes include plants and plankton, while in marine ecosystems, phytoplankton serve as the main primary producers.

Step-by-step explanation:

The statement that does not accurately describe freshwater and saltwater ecosystems is: b. The primary producers in saltwater and freshwater ecosystems are amoebas. In reality, the primary producers in these ecosystems are different. In freshwater ecosystems such as lakes, ponds, rivers, streams, and wetlands, the primary producers are often plants and plankton, adapted to the low salt content. In contrast, marine ecosystems, including oceans, coral reefs, and estuaries, have phytoplankton as primary producers, which perform a significant portion of Earth's photosynthesis. Freshwater ecosystems have a very low salt concentration, while saltwater ecosystems have a high salt concentration and support diverse life forms adapted to salty conditions.
