Autotrophs use solar or chemical energy to produce food. Primary producers are the first producers of energy-rich compounds that are later used by other organisms. The most common primary producers use solar energy to harness photosynthesis - plants. Photosynthesis uses light energy to power chemical reactions that convert carbon dioxide and water into oxygen and sugars or starches. Biologists discovered life deep below the ocean surface on the ocean floor in total darkness.
The first trophic level contains the greatest number of organisms and is comprised mainly of plants. The organisms in this layer are called primary producers because they get their energy from an abiotic source. Most primary producers get their energy directly from the sun.his lesson will explore the feeding relationships of organisms in an ecosystem, including food chains and food webs. The lesson will also investigate the different trophic levels of a food chain and give examples of species found at each level.
