When a short nonfiction piece compares two ecosystems, what is a key strategy?

• A. Focus on a single ecosystem
• B. Identify similarities and differences in climate, plants, and animals
• C. Describe the weather only
• D. List random facts

Answer: (B)

Comparing two ecosystems works best when you identify what is similar and what is different across climate, plants, and animals. This lets readers see how the environment shapes the living things and why each ecosystem has its own distinctive community and adaptations. Focusing on a single ecosystem would miss how the two environments relate to one another. Describing only the weather narrows the discussion to conditions rather than the full living system, and listing random facts offers little organization or purpose. By tracing similarities and differences in climate, plants, and animals, the short nonfiction piece provides a clear, informative picture of how each ecosystem works and how they compare.
