Question

Which would be an autotroph in a grassland ecosystem? (1 point)
• mallard duck
• monarch butterfly
• prairie cordgrass
• muskrat

Answer 1

In a grassland ecosystem, the autotroph would be **prairie cordgrass**. Autotrophs are organisms that produce their own food through processes like photosynthesis, and prairie cordgrass is a plant that does this. The other options (mallard duck, monarch butterfly, and muskrat) are heterotrophs, as they consume other organisms for energy.
