Question

1. over the course of what years did this study take place?
2. in the space below, draw two light colored trees. on one tree, draw a light - colored moth. on the other, draw a dark colored moth.
3. the light - colored tree represents a birch tree in the 1850s. the dark represents a tree around 1900. if you were a bird seeking out food in 1850, which moth would be easier to spot? why?
4. describe the change in environment that took place during the industrial revolution.
5. describe the change in population from 1850 to 1900.
6. which moths were better adapted for their environment in 1850? which ones in 1900?
7. did the moths spontaneously change from light to dark and vice versa? why or why not?

Explanation:

This set of questions relates to the study of peppered moths and industrial melanism, which falls under the subfield of Biology (Natural Science). The questions involve concepts like natural selection, adaptation, and environmental change over time (industrial revolution's impact on ecosystems). For example, question 4 asks about predator - prey interactions and camouflage, question 5 about environmental changes during industrial revolution, and question 7 about adaptation of moths. These are core topics in Biology, specifically in the area of evolutionary biology and ecology.

Answer:

The subfield is Biology (under Natural Science).
