Answer: Tree and Grass are the two correct answers here
Explanation: Producers are photosynthesizing organisms. They are any kind of green plant that make their food by taking sunlight and using the energy to make sugar.
Producers make their own food. Trees and grass can make their own food using sunlight (photosynthesis). Monkey is consumer (eats other things like bananas- made by plants - for survival). Mold (like fungus) eat dead stuff and thus are decomposers (not producers).
