In ecological and biological topics, “producers (organisms)” refers specifically to autotrophic organisms that synthesize organic compounds from inorganic substrates, forming the energetic and biomass foundation of ecosystems. Primary producers, such as photosynthetic plants, algae, and cyanobacteria, convert light energy into chemical energy via photosynthesis, fixing carbon dioxide into carbohydrates and releasing oxygen. Some bacteria function as chemoautotrophic producers, using chemical energy from inorganic reactions (e.g., oxidation of hydrogen sulfide or ammonia) to fix carbon. Producers determine primary productivity, regulate biogeochemical cycles, and constrain energy flow and trophic structure across terrestrial, freshwater, and marine ecosystems.
A specific cellular mechanism regulates the protein balance of plants, thereby influencing how they respond to environmental stress. An international research team led by Dr. Markus Wirtz at the Center for Organismal Studies ...

Winter in Antarctica is long and dark. Temperatures remain well below freezing. In many places, the sun sets in April and does not rise above the horizon again until August. Without sunlight, photosynthetic life such as plants, ...

By 2100, Australian and global coral reef communities will be slow to recover, less complex, and dominated by fleshy algae, as high carbon dioxide changes ocean chemistry.
