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 10
A field is abandoned and over several decades, it becomes a forest. What type of succession is this?
Describe how succession can lead to increased soil fertility.
Describe the main difference between primary and secondary succession.
Describe the role of decomposers in ecological succession.
