1. What are the products of photosynthesis?

carbon dioxide and water
glucose and oxygen
light and dark

2. What colour is chlorophyll?

red.
blue.
green.

3. Where does photosynthesis take place?

in the chloroplast
in the cell wall
in the nucleus

4. A green plant is usually a:

producer
consumer
director

5. What does a food chain always start with?

a top predator
a herbivore
a producer

6. Which is the secondary consumer in this food chain:
grass -> grasshopper -> frog -> hawk

grass
grasshopper
frogs

animals only
plants only
animals and plants

8. What is wrong with this pyramid of numbers?

from top to bottom: the sparrowhawk is represented by a thin bar, the thrush is represented by a slightly thicker bar, the clover has the widest bar in this pyramid, and the snail is at the bottom with a slightly narrower bar than the clover

hawks don't eat thrushes
the clover should be at the bottom
snails don't eat clover

9. What can we conclude from this pyramid of numbers?

There is a small bar for the producer, a very large bar for the primary consumer, and a smaller bar for the secondary consumer

the producer must be very large
the producer must be very small
the primary consumer must be a carnivore
