• Draw a diagram containing the 5 kingdoms in order

• Consider the following a population of Moths lives in a
white birch forest which is for 100s of years untouched
by man. Very suddenly man starts to build power
plants and factories near by. The smoke from the plants
stains the white birch bark black.
– Prior to the plant and factory pollution there were about

stained the trees the ratio of the population changed to
60% black and 40% white. Explain why this happened.

changed the population might have been.
