Explanation
Answer: D - Ponds, grasslands, and forests are examples of ecosystems.
Key Takeaway: The ecosystem is a natural unit consisting of all plants, animals, and microorganisms (biotic factors) in an area functioning in conjunction with the physical (abiotic) factors of the environment. While ecosystem is often used interchangeably with biome, the terms define different areas. In short, a biome is comprised of numerous ecosystems. Like the ecosystem, the biome is a defined area of ecologically similar climatic conditions, but defined to a much larger area.
