Question
Describe the population of peppered moth
in England before, during, and after the
industrial revolution? How is it Natural
Selection?
Answer:
• Pre I.R.
2 types of peppered moth (white and black). White is
dominate variety (hide on white birch tree) while black are the
lower # population (can be seen on white tree and are eaten).
• During I.R.
Pollution cause white trees to turn black. White variety moth
are now seen and eaten while the black moths are now
hidden. Decrease in White population and Increase in Black
population
• Post I.R.
Clean up processes after the I.R. not as much smoke in air.
Trees turn white, white moth hides and their population goes
up. Black moth is seen and eaten, population goes down
• Natural Selection because nature selected
certain traits to be passed on in a society.
The makeup of the population changed as
nature changed.

Question
Why is the realized niche of a species more
specialized than its fundamental niche?
Answer:
•Fundamental niche is the entire niche of an
organism. When the niches overlap, competition
happens. To avoid competition the organism
creates a realized niche that is smaller and
without competition.
