Middle School Life Science Flashcards: Justify Conservation Choices

Study Justify Conservation Choices in Middle School Life Science with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

Which evidence is more reliable: one sample or n=10n=10 samples collected the same way?

ANSWER

n=10n=10 samples collected the same way. Larger sample sizes reduce random variation.

Students are evaluating conservation plans for a wetland that filters water and provides habitat for frogs. Frog numbers have dropped. Criteria: (1) Scientific effectiveness (improve frog breeding success), (2) Economic cost, (3) Social feasibility for nearby homeowners. Evidence:
  • Water tests show high nitrate levels after rainstorms.
  • Frogs lay eggs in shallow areas with native plants.
  • Option A: Restore native wetland plants along 2 km of shoreline. Studies show nitrate levels drop 20% and frog egg survival increases 15% in 1 year. Cost: $70,000.
  • Option B: Drain the wetland, remove mud, and refill it. Could reduce nitrates short-term, but removes current habitat for at least 1 breeding season. Cost: $200,000.
  • Option C: Add fish that eat mosquito larvae. Studies show mosquitoes decrease, but fish also eat frog eggs; frog breeding success decreases 10%. Cost: $10,000.
Constraints: Budget is $80,000. Homeowners require that the wetland remain filled with water year-round. Which statement best justifies a conservation solution using evidence and constraints?
