HELP PLEASE!!! Juanita recorded the number of each species in water samples taken at three different distances away from a sewage outlet. her results are shown on the right.
distance-1 no.of mayfly larvae-3 no. of sludge worms-20
distance-2/no. of mayfly larvae-11/no.of sludge worms-14
distance-3/no. of mayfly larvae-23/no. of sludge worms-7
b)give one thing that she would have to do to make this experiment a fair test.
c)what can you conclude about the two organisms from these results?
d) suggest why sewage may decrease the number of mayfly larvae

is each distance further away?

trancenova · Answer

For question (c) consider what differences in responses there were between the species (and possibly what this may reflect on the organisms themselves)

trancenova · Answer

Take a look at this diagram and think about the differences in responses of the two species
(mayfly= empty box, worm = box with lines)
