Document Summary
Energy and nutrients pass from primary producers . Build molecules themselves using photosynthesis or chemiosmosis as an. Depend on the biosynthetic output of other organisms. (autotrophs) to primary consumers (herbivores) to secondary consumers that feed on other carnivores) , are heterotrophs that derive their energy from detritus . Prokaryotes and fungi are the main detritivores. Energy and other limiting factors control primary production. In some ecosystems, chemoautotrophs are the primary producers chemical energy by autotrophs during a given time period. Is the amount of light energy converted to. An autotroph is an organism able to make its own food. Autotrophic organisms take inorganic substances into their bodies and transform them into organic nourishment. Use light energy to make organic substances (food) Use chemical energy (hydrogen sulfide, ammonium and other agents). These organisms (chemoautotrophs( are usually found in extreme environments - hydrothermal vents or underground or ice. The extent of photosynthetic production sets the spending limit for an ecosystem"s energy budget.
