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 9
A bird eats ticks off a buffalo’s back. What type of interaction is this?
A case study: In a forest, woodpeckers create holes in trees. Later, other birds use these holes for nesting. What type of interaction is this?
A fungus grows on a tree, taking nutrients and causing the tree to weaken. What type of interaction is this?
A scenario: A cuckoo lays its eggs in the nest of another bird, which then raises the cuckoo chick. What type of interaction is this?
