Ecological Succession
Biology ⇒ Ecology and Environment
Ecological Succession starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Ecological Succession.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A forest is cleared by logging, but the soil remains. What type of succession will follow, and why?
A volcanic eruption creates a new island. Which type of succession will occur, and what will be the first colonizers?
Describe how animal species composition changes during succession.
Describe the main difference between primary and secondary succession.
Describe the process of soil formation during primary succession.
Describe the role of disturbances in maintaining ecosystem diversity.
