Title:
Natural Selection Activity Worksheet
Your name: Cydney Buford
Instructor's name: Morgan Smith
Name of this activity: 02.04 Adaptation and Succession
Hypotheses: If I investigate the environment with snow, then I will observe an increase in population of white rabbits over time.

The independent variable are the white and brown rabbits, and the dependent variable is the light and dark environment
2.
Describe the relationship among them. The light environment lets the white rabbit population increase
and makes the brown rabbit more vulnerable to being eaten by predators. The dark environment lets the brown rabbit population increase and the white rabbit population decreases. 3.
Explain the patterns observed in the lab activity. What conclusions about adaptation and natural selection can be drawn pertaining to survival of a species based on the pattern observed? Justify your conclusions. The patterns in this lab are that by the 5 generation depending on the environment one of the types of rabbits will be 0. With natural selection predators would be prone to selecting the rabbits they can see the best.
4.
Explain
how the numbers might look if instead of changing environments, there was a change in climate. Make sure to be specific in what change you are considering and why it would guide the changes in the populations.
5.
In the dark environment, all trees were removed due to deforestation practices. Identify
the type of succession this is. Explain
how this ecological event impacts the survival rates of both color types of rabbits and the predator. The survival rate of the white rabbits will still be decreasing since their in a dark environment, brown rabbits will decrease because it will be easier for the predators to see them. The predators will have more food to eat.`
