Answer:
Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it.
Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic.
Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules.
Chemoautotrophs are usually bacteria that live in ecosystems where sunlight is unavailable.
Heterotrophs cannot synthesize their own energy, but must obtain it from autotrophs or other heterotrophs; they act as consumers in food webs.
