Primary producers are seen as the first level of any food web. Name organisms that act as the primary producers on land, in the oceans and in the deep parts of the ocean.
On land, primary producers can include plants such as grasses, trees, shrubs, and mosses. In the oceans, primary producers can include phytoplankton, seaweed, and algae. In the deep parts of the ocean, primary producers can include chemosynthetic bacteria that use chemical energy from hydrothermal vents as their energy source rather than sunlight.
Primary producers on land are typically plants, such as grasses, trees, and shrubs. In the oceans, primary producers include microscopic plants called phytoplankton, as well as larger algae. In the deep parts of the ocean, where sunlight is limited, primary producers often rely on chemosynthesis rather than photosynthesis. These chemosynthetic primary producers include bacteria and archaea that can convert chemicals, such as hydrogen sulfide or methane, into organic matter. Examples of deep-sea chemosynthetic organisms are giant tube worms, clams, and certain types of bacteria.
