Compound nouns combine words into one concept: nature reserve, food chain, greenhouse gas, wildlife protection. The final noun usually determines the plural: nature reserves, food chains. Some compounds are written as one word, some separately or with a hyphen; check established usage. Stress often falls earlier in noun compounds, but patterns vary. Choose a compound for meaning rather than merely placing any two nouns together.
The stream is cleaner, isn’t it? ↘ (seeking agreement); You have checked the source, haven’t you? ↗ (genuine uncertainty). Falling tags often expect agreement; rising tags often check information. Context matters. Keep auxiliary and pronoun agreement: They can help, can’t they? Do not treat every tag as a request for confirmation with the same certainty.
We can protect biodiversity by keeping to paths, avoiding wildlife feeding and reporting damage responsibly. If people remove bank plants, erosion may increase; that is a prediction to investigate, not a result we have measured. Shall we ask the specialist which plants are suitable before proposing restoration? I would rather prevent further damage than organise an unsupervised planting event. For a school information project, we could explain a food chain with arrows from food to consumer and observe from authorised public points. We should record dates, weather and the method used. Not seeing an animal does not prove that it is absent, and water appearance alone does not measure chemical quality. These limits belong in our presentation. Protecting an ecosystem means supporting its relationships and processes, not merely arranging an attractive photograph.
Follow-up: Can we release animals to restore the stream?
Response: No. Introducing organisms requires specialist and official decisions; it is not a school experiment.

Original writing model for the final two review tasks
Local ecosystem restoration deserves public funding when the work addresses a clear need and is checked carefully. A healthy wetland can provide habitat and support natural processes that are difficult to replace. However, spending money on a visible planting event is not enough. The chosen species must suit the site, and maintenance and monitoring need long-term resources. Residents should also be consulted so that access and livelihoods are considered. I would support a project that begins with a survey of existing conditions, uses specialist advice and publishes realistic measures of progress. I would question a proposal that promises immediate recovery without evidence. Restoration is a commitment to ecological function, not merely an attractive photograph or a large number of seedlings.
Write a short final paragraph or spoken conclusion that preserves the model’s message. Use details already supplied, not invented results.
