5. The following information shows the steps in investigating the factors of
competition among plants.
a) Arrange the following steps in the correct order.

Q Pour the same volume of water in both containers daily.
R After two weeks, compare the growth of the corn seedlings.
S Prepare two planting containers of the same size and fill the
containers with equal amount of soil. Label the containers X
and Y.
b) What are the factors of competition between the plants identified
from the steps above?
6. An investigation was conducted by a group of Science Club members on
two prawns from two different prawn culture ponds. The pictures below
show the observations and data they collected.
Pond A Pond B
mass: 14 grams mass: 8 grams
a) Based on the information above, give two suitable inferences on the
differences observed.
b) By selecting one of the inferences you gave in (a), provide another
observation to support that inference.
