In terrestrial ecosystems, which organism is most likely a primary producer?

Explanation:
Primary producers are autotrophs that convert light energy into organic matter, forming the base of the food web. In terrestrial ecosystems, photosynthetic plants do this, turning sunlight and CO2 into sugars that build biomass. Grass fits this role perfectly, using photosynthesis to produce the energy and matter that other organisms rely on. A rabbit eats the grass and acts as a primary consumer, the hawk is a predator further up the chain, and fungi usually decompose organic material rather than producing their own energy through photosynthesis. So grass is the primary producer.
