Answer questions about how ecosystems work and how energy flows. Covers trophic levels, population interactions, cycles, and major biome features.
Pick a difficulty and question count to begin.
Food webs can look complicated, but the core ideas are simple: who eats whom, and how energy flows. This quiz helps you recognize roles in an ecosystem and connect them to common biome conditions.
You’ll answer multiple-choice questions with 4 options each and no timer, so you can think through each scenario without rushing.
This set is labeled Easy, so questions focus on definitions, straightforward examples, and common organisms found in major biomes. You can choose your question count before you start; selecting more questions gives you broader coverage, while fewer questions makes for a quick review.
If difficulty settings are available on your start panel, moving up from Easy typically adds more complex food web interactions, indirect effects, and trickier biome comparisons.
Questions are balanced to cover both food web structure and biome basics, with a mix of recall and light reasoning. Distractors (wrong options) are written to reflect common misconceptions, so your score highlights exactly what to revisit.
What is the primary producer in an aquatic food web?
Which biome is characterized by low rainfall and extreme temperatures?
What term describes organisms that obtain energy by consuming other organisms?
Yes. The Easy setting focuses on core vocabulary (producer/consumer/decomposer), basic trophic levels, and simple biome characteristics.
Each question has 4 multiple-choice options.
No. The quiz has no timer, so you can work at your own pace.
Use the start panel to choose your question count before beginning; more questions means more practice across topics.
Your score reflects how well you identify organism roles, energy flow, and biome traits; missed questions often point to common mix-ups like chain vs. web or decomposer vs. scavenger.
Test your knowledge of major human body systems and what they do. Covers organs, system interactions, and basic physiology terms.
Test core physics concepts behind everyday motion. Covers Newton’s laws, friction, work and energy, momentum, and simple conceptual scenarios.
Check your understanding of objects and processes in space. Covers star life cycles, planet types, galaxies, and basic observational astronomy terms.
Identify how element properties change across periods and down groups. Covers electronegativity, ionization energy, atomic radius, and common families.
Explore how traits are inherited through genes and alleles. Covers Mendelian inheritance, dominant/recessive patterns, and simple Punnett-square reasoning.

Match the names behind the titles in this U.S. Presidents quiz focused on cabinet officers and vice presidents. You’ll identify which administration each figure served in, from well-known pairings to trickier historical overlaps. Great for sharpening your timeline sense and avoiding common name-and-era mix-ups.
