The primary producers of the ocean are microscopic phytoplankton, including protists like algae and diatoms. Show The majority of marine consumers are planktonic, including protists and small animals.  Most decomposition is carried out by species of bacteria, enabling nutrients to cycle back to producers. Massive numbers of phytoplankton are needed to support higher trophic (feeding) levels. Fluctuations in phytoplankton can impact krill, and many consumers rely of krill as a primary food source. Most marine producers are tiny, but there several notable macro(large) producers including the seaweeds. Seaweeds are not plants, they are actually large algae. You can tell by squishing fresh seaweed between your fingers: it squishes easily unlike the more structured plants. Kelp, algae and diatoms are all classified in Domain Eukaryota and Kingdom _____. Kelp is algae (seaweed) that grows along many coastlines and appears like an underwater forest. These sea otters have wrapped emerging kelp around their bodies to stay in place as they sleep. There are some marine plants like this sea grass, but sea plants are primarily found around coastlines. Marine plants are no where near as abundant as algae, diatoms, dinoflagellates, bacteria and archaea producers. Kelp and other “seaweeds” are protists, not plants. We’re going to take a minute to revisit Kingdom Protista. Most Protists are microscopic aquatic producers or consumers. The decomposer species were the relatively uncommon terrestrial slime molds. Similar to the freshwater pond samples, there are species of algae and diatoms in marine water. Dinoflagellates in saltwater are associated with “red tides” of toxic chemicals, but some species play an important mutualistic role with coral animals. Common freshwater consumer protists include paramecia and amoeba. In saltwater there are many consumer species, including Formanifera that look like tiny snail shells, but are not animals.

Is play an important role as producer in an aquatic ecosystem?Phytoplankton is essential for the aquatic ecosystem. They play a significant role in providing food to many species residing in an ecosystem. They act as primary producers, which means they are the main source of food in an entire food web of the aquatic ecosystem.
What are producers?Definition: A producer is someone who creates and supplies goods or services. Producers combine labor and capital—called factor inputs—to create—that is, to output—something else. Business firms are the main examples of producers and are usually what economists have in mind when talking about producers.
Where are most producers likely to be found in a lake ecosystem?Macrophytes are generally the most visible group of primary producers in lakes and ponds (Figure 2). Macrophyte species possess a diversity of growth forms. Emergent macrophytes undergo photosynthesis above the water and are typically found close to the shoreline.
What is an example of a producer in a terrestrial ecosystem?Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark. Trees, such as they mighty Oak, and the grand American Beech, are examples of producers.
