Ecological Succession

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 9
A field is abandoned after years of farming. Over time, grasses, shrubs, and then trees begin to grow. What type of succession is this?
A pond gradually fills with sediment and becomes a meadow. What is this process called?
A volcanic eruption creates a new island. What type of succession will occur on this island?
Describe the difference between autogenic and allogenic succession.
Describe the main difference between primary and secondary succession.
