Question:
Why might a scientist want to know how many lady bugs are
in a neighborhood or prarie?
Replies:
They might want to know how many ladybugs there are to see if they are
growing smaller or larger in number from year to year. They might want to
compare the number to the number of ladybugs in another area. They might
even want to see if current weather has effected their numbers, or if they
ladybugs are effecting the plants in the area.
