Community Interactions starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Community Interactions.
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

Describe how the presence of a dominant competitor can affect species diversity in a community.
Describe the concept of resource partitioning and its significance in community interactions.
Describe the difference between facultative and obligate mutualism.
