Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.86 Biotic and Abiotic Factors. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Biotic and Abiotic Factors: Students identify living and nonliving factors and predict how light, temperature, water, nutrients, salinity, space, and pH affect organisms. Rigor range: standard concept checks through honors/Pre-AP/AP-ready quantitative ecosystem modeling, systems analysis, and solution trade-off evaluation.

Sample Practice Problems

Preview the types of problems and questions covered in this worksheet

Below are sample questions representative of the exercises included on this worksheet and related 10.86 Biotic and Abiotic Factors skill assessments:

Problem 1Difficulty: Mastery

A proposal to deepen an urban pond would reduce summer heating but remove shallow, well-lit habitat for rooted plants. Which evaluation is most appropriate?

AApprove the proposal because reducing one stressor has no trade-offs.

BReject all abiotic data because only organisms matter.

CCompare cooler-water benefits with the loss of lighted space for rooted plants.

DAssume deeper water increases light at the bottom.

Solution & Explanation:Deepening changes multiple abiotic factors. It may reduce heat stress while also reducing shallow, lighted space needed by rooted plants.

Problem 2Difficulty: Mastery

Use the nonlinear survival curve for salmon embryos across temperature. What is the best prediction if stream temperature rises from 10 C to 18 C?

ASurvival will increase because warmer is always better.

BSurvival will decline sharply as temperature approaches the upper tolerance range.

CSurvival will remain exactly the same at all temperatures.

DTemperature cannot affect embryos because they are biotic.

Solution & Explanation:The curve shows high survival around 10 C but much lower survival at 18 C. Warming toward the upper tolerance range is predicted to reduce survival.

Problem 3Difficulty: Mastery

Liebig's law suggests growth is limited by the scarcest required resource relative to need. If nitrate is sufficient, phosphate is very low, and light is high, what should most increase algal growth?

Aadding phosphate

Badding nitrate only

Cremoving light

Dlowering all nutrients

Solution & Explanation:If phosphate is the scarcest required resource, it is the limiting factor. Adding more of a sufficient nutrient is less likely to increase growth.
