What would explain this observation?
- Breeding endangered animals without protecting suitable habitat may leave nowhere for them to survive. Conservation · Conservación 保护 measures need to work together.
- Start with a prediction. State the quantities or features you would compare, then decide what evidence could distinguish two explanations.
Build the model
- Conservation programmes can breed endangered species and protect or regenerate rare habitats. Field margins and hedgerows restore shelter and resources around single-crop fields. Reducing deforestation and carbon-dioxide emissions can limit wider pressures. Recycling resources reduces demand for some new materials and landfill disposal.
- conservation: Actions maintaining species and functioning habitats; habitat regeneration 生境恢复: Recovery or restoration of a habitat’s condition.
Which plan addresses both a species and its living conditions?
Each measure has benefits and limitations. Breeding needs genetic diversity and suitable release conditions; habitat restoration takes time; land set aside for biodiversity may compete with production. Human interactions can be positive or negative depending on the action and its context. A justified evaluation weighs evidence and conflicting pressures rather than listing only advantages.
Match each technical term to its precise meaning.
Use the definitions to distinguish related quantities and processes.
Choose evidence that can test it

Human interactions can be positive or negative depending on the action and its context. A justified evaluation weighs evidence and conflicting pressures rather than listing only advantages.
- Compare supplied proposals with costs, species records and local needs. State which mechanism each action targets and propose matched monitoring before and after implementation. Use equal survey effort and suitable comparison areas where possible. Do not release captive organisms or introduce species as a classroom experiment.
Which two habits make the investigation or model in this case more defensible?
Compare supplied proposals with costs, species records and local needs. State which mechanism each action targets and propose matched monitoring before and after implementation. Use equal survey effort and suitable comparison areas where possible. Do not release captive organisms or introduce species as a classroom experiment.
Work from known quantities
- State the known values and their units. Choose the relation because its assumptions fit this case, then rearrange before substitution.
- Known: equal-effort surveys record 8 species before a fictional habitat programme and 12 afterwards. Increase = 4 species, or 50% of the initial recorded richness. A comparison site and repeated seasons would help determine whether the programme contributed to the change.
Recorded richness rises from 10 to 15 species under equal sampling. Find percentage increase. Use the same sequence: known quantities → model → relation → substitution → unit and interpretation.

The result is 50 %. Known: equal-effort surveys record 8 species before a fictional habitat programme and 12 afterwards. Increase = 4 species, or 50% of the initial recorded richness. A comparison site and repeated seasons would help determine whether the programme contributed to the change.
Check the conclusion and its limits
- A larger release count alone does not show successful conservation. A field margin supports more than decorative plants: it can provide food, shelter and connectivity. Recycling cannot repair every habitat already lost, so different measures address different pressures.
- Return to the original observation. Explain what the result supports, which conditions it assumes, and one way to test a competing explanation.
Releasing more captive animals proves their wild population is sustainable. This claim is false: A larger release count alone does not show successful conservation. A field margin supports more than decorative plants: it can provide food, shelter and connectivity. Recycling cannot repair every habitat already lost, so different measures address different pressures.
