Ecosystems, Habitats & Biomes — Drills · Grade 6 Science
Chapter: Ecosystems, Watersheds & ConservationWhat these drills covers
By the end of Ecosystems, Habitats & Biomes you should be able to:
- I can distinguish a habitat, a population, a community and an ecosystem.
- I can explain how temperature and rainfall determine which biome occurs in a place.
- I can explain why similar-looking species evolve in separate continents with the same climate.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: habitat, species richness, evidence, system boundary, uncertainty.
Problem 1
- A biome label establishes identical conditions at every site.
- More individuals always means more species.
- habitat: The setting and conditions an organism uses to live and obtain resources.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
habitat: The setting and conditions an organism uses to live and obtain resources.
The setting and conditions an organism uses to live and obtain resources.
Problem 2
- Repeating any method makes every causal claim true.
- A biome label establishes identical conditions at every site.
- More individuals always means more species.
- species richness: The number of different species recorded under a stated method.
Answer and explanation
species richness: The number of different species recorded under a stated method.
The number of different species recorded under a stated method.
Problem 3
Answer and explanation
Use comparable soil and sampling conditions, repeated observations, and moisture records while evaluating other differences.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 4
Answer and explanation
It determines which conditions, interactions, and movements the study includes and limits the population-level conclusion.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
