Likewise, producers in an aquatic ecosystem are various species like phytoplankton, algae and higher plants. What Is Biodiversity (Biological Diversity)? After generating their energy from the sun, plants pass the energy on to the primary consumers. Producers are those who prepare their own food, so all green plants who prepare heir own food are considered as Producers. Primary producers, also known as autotrophs, are the basis of every ecosystems food chain, including the tropical rain forest, since they generate their own food and give energy to other levels of the food chain via photosynthesis.
