Answer

Saprotrophs decompose organic matter; Photoautotrophs use photosynthesis; Chemoautotrophs oxidize inorganic substances. Explanation 1. Describe Energy Acquisition by Saprotrophs Saprotrophs obtain energy by decomposing organic matter. They break down dead or decaying organisms, absorbing nutrients released during the process. 2. Describe Energy Acquisition by Photoautotrophs Photoautotrophs capture light energy through photosynthesis. They convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen. 3. Describe Energy Acquisition by Chemoautotrophs Chemoautotrophs derive energy from inorganic chemical reactions. They oxidize inorganic substances (e.g., hydrogen sulfide, ammonia) to synthesize organic compounds without sunlight.
