Which organism is a producer in a simple ecosystem?

• A. Rabbit
• B. Hawk
• C. Grass
• D. Decomposer

Answer: (C)

Energy in a simple ecosystem starts with producers—organisms that make their own food using sunlight. Grass does this through photosynthesis, turning light energy into chemical energy stored as sugars. This stored energy becomes the food source for other organisms, like herbivores that eat the grass and predators that eat those herbivores. Decomposers, on the other hand, break down dead material and recycle nutrients rather than making new food. So the organism that serves as the energy producer is grass.
