What is the Biology Basic Ecosystem and Biodiversity Quiz?
This is a free, unofficial 4-choice quiz app for reviewing ecosystems and biodiversity in high school Biology Basic, including food chains, food webs, conservation, invasive species, energy flow, material cycles, and data reading.
The questions, options, explanations, and diagrams are original. They are not copied from textbooks, workbooks, entrance exams, mock exams, handouts, slides, or official PDFs.
Original practice topics
The app covers food chains, food webs, producers, consumers, decomposers, energy flow, material cycles, populations, communities, species interactions, biodiversity levels, ecosystem services, conservation, invasive species, habitat fragmentation, eutrophication, and original data-reading scenarios.

Dynamic hints with original diagrams
Hints change according to the current question. Food chains, energy pyramids, biodiversity levels, material cycles, conservation corridors, and observation data are shown using original SVG diagrams.
My Page stores challenge history, best records, and often missed questions for repeated review.
How this quiz can be used
Students can use short 10-question sessions after class, then move to longer mixed courses before a test. Teachers and parents can also use the course list as a quick way to choose a review topic.
The questions focus on reading relationships: who eats whom, what changes first, whether a claim is supported by data, and which conservation action matches the cause of the problem.
Learn with hints, not memorization alone
For each question, the hint explains where to look first. For example, a food-chain question highlights arrow direction, a data question highlights values, and a conservation question highlights the cause of the environmental change.
The diagrams are intentionally simple so learners can check the idea quickly on a phone or tablet.
