Is grass a chemotroph

No, grass is not a chemotroph; it is classified as a phototroph. Grass, like other plants, primarily obtains energy through photosynthesis, using sunlight to convert carbon dioxide and water into glucose and oxygen. Chemotrophs, on the other hand, derive energy from chemical reactions, typically by oxidizing inorganic or organic compounds. Thus, grass relies on light energy rather than chemical compounds for its energy needs.
