This free web app helps students review vegetation and ecological succession in a 4-choice quiz format.
The questions are original and cover forests, grasslands, primary succession, secondary succession, pioneer species, soil formation, light conditions, and simple observation-style scenarios.
The quiz does not reproduce textbook passages, workbook exercises, entrance exam questions, mock exam items, or copied diagrams.
Questions, choices, explanations, observation settings, numerical settings, and diagrams are independently created for this site.
You can review the difference between primary and secondary succession, the role of pioneer species, soil formation, forest layers, and the relationship between light conditions and plant growth.
The quiz also includes dry and wet succession, sun trees and shade trees, mixed forests, climax communities, disturbance, forest gaps, and simple climate or observation-data reading.
Each course is short enough for a quick review before class, after homework, or before a regular test. The hint button shows diagrams and step-by-step clues that match the current question.
Challenge history and often missed questions can be checked from My Page, so students can return to weak points such as succession order, soil, light, and biome reasoning.
