Grade 6 :
1. The fox and the owl are both
(a) finding a mate.
(b) competing for food.
(c) seeking shelter.
(d) migrating for winter.
2. Since green plants make their own food, they are called
(a) predators.
(b) prey.
(c) decomposers.
(d) producers.
3. Which structure of a bird is correctly paired with its function?

(b) Wings for eliminating waste.
(c) Feathers for breathing.
(d) Eyes for growing.
4. Predators such as wolves and coyotes – and even bears – are moving closer to highly populated areas.

Which of the following best explains the change?
(a) Light-coloured mice can run faster.
(b) Dark-coloured mice have fewer offspring.
(c) Light-coloured mice have changed colour over generations.
(d) Dark-coloured mice are better able to hide from their predators.
6. When two animals live in the same area and depend on the same organism for food, they are
(a) competing.
(b) decomposing.
(c) germinating.
(d) hibernating.
7. Why do some animals hibernate in the winter?
(a) To find food for their young.
(b) To adapt to environmental changes.
(c) To attract a mate.
(d) To avoid predators.
8. A spider building its web is an example of
